I have now 2 versions of FH2 running side by side.
One 2.45 and 2.52.
As for the 2.52 and latest Map-Pack: Beda Fomm + Arty Cam,
the Artillery Camera is indeed the cause, the last entry from the .con
pointing to the .tweak file is missing. That causes the crash when
requesting artillery fire.

...\fh2\objects_weapons_server.zip\Weapons\Common\artillerycamera_de\artillerycamera_de.con

leave a blank line at the bottom and paste this in

include artillerycamera_de.tweak

I jumped upon this as I see both the Mortars and this artillery camera have been tweaked
at the same timeline.
First I had the same crash, after editing, all fine, arty cam back.

Edit:

Just jumped over Reichswald, what a jolly good Map. Fitting like a glove. I like it
when Axis is pushed to Schottheide, awesome fierce fighting.
Thanks for adding this Map.

Use Search function and human function to read through Posts,
if you grassed up here and found it's not enough go to Google
and start over... The Threads are there, but nobody takes you by the hand.

You need to find most by playing a Map again and again.
Even then it is a matter of taste.

Fall of Tobruk/Axis (at later stages/Cap-Points positive to avoid flanking)

Between Aussie Main wooden stairs and the large Tanks at Harbour Outskirts
you'll see two Ruins, chose the one on the right side if facing Aussie Main from Harbour.
Crouch inside, then you can enter a part of the ruin compartment under comfortable floors.
This is a vital position that will free you from heavy Barrage as expected in the closer compound to
that main. The Mortar shells halfway to Harbour and the Hotel area, see this estimated
Map, as well a screenshot showing this position. I use to have a good sight even to the front,
thanks to a door opening where you can trace them walking for you.
If you ran out of Ammo, Harbour Cap Point is the best choice, just watch for Hostiles, Bullets.
You can easilly re-enter that Spot then.

I made an alternate Vossenack, where some Vehicles are almost never unused, even if under Shelter.
I can't recall the changes I made, but as soon as I return to default setup, they act as non-interesting to bots and that surplus to 70% of the inventory.
I was simply cloning some of the spawnboxes, on others I gave them new Boxes, the mix of
both made it. My version has no unused Vehicle, though it is a Tank frenzy. Main problem on Vossenack for Bots in Vehicles, is everything East of Church area, the objects are good enough for Human to drive trhough with a Vehicle, but for Bots this area is a messy adventure, they stuck at literally every object placed a bit on the streets. Ever wondered why the rush-out on Vossenack Axis Main is stuck before the wooden fence, it is one of this Wooden fence objects possibly seen as unpassable. When trying to drive trough you actually sense some object you pass, not like the other passable fence objects.
In notepad I've seen that this fenceobject is littered all across the Map and the reason for some areas not passable for Bots, although Navmeshed, as they want to pass.
I tried 2 version removing them completely, or changing with passable fences. Returning to stock layout I can't pass one of this section though, my tank just slides upwards on that fence. It is the vertical object of that fence part that remains unpassable/solid and causing laggs.
By removing that fence object, the Map has a 50% rush, that you can enjoy playing. The consolidated Vehicles spawns are surplus additions to the default very slow going Map.

They get trapped before entering neat points, Axis at entrance, where the Anti-Tank barrier resides, you can free this area from litter, 3 up to 5 vehicles still stuck, sth. initially slowing down the push of the Map, so I think it is some sort of neat point of Vehicle Navmesh causing culprit. To really get hell-of a tanking Map, it needs to get rid of such tiny hangers, more Bot-friendly Navmesh, but that calls for less litter in Church area and really closer look at all objects and make them passable, luckily this Map didn't need much overhaul, just a bit consolidation.
Apart from that it is a careless Map, I can only recall one major thing that needed overhaul, the 88 on that hill trench.
needs some lifting, as the bushes/vegetation cover the gunsight aiming, I put her on an
palette object slightly lifted, now the gunsight is free and good to use.

Darman, can't recall the trouble now, all fine. Just stumbled over the great
Presentation and work of these new Additions, awesome.
Incredible Christmas surprise, thanks Mate

I could solve the CTD, was a due to a Kits conflict.
Though the flickering of the Skydome Texture is imminent,
the Texture frequently turns into bright white overall,
every 15 secs?!

Your renewed current Beda-Fomm Sky would be perfect, I like the
fogsettings blending in the terrain. But the sun Flare position is wrong,
in order to solve, you must get an old FH2 Texture Gazala.dds (i.e. FH2 2.1) and
rework the Sky.con (Beda_Fomm_Final.rar) accordingly.
I'm testing some settings from you on this.
Thanks for your efforts

Some time ago I had nothing better to do than this.
Tweak your Fall of Tobruk, to engage some underground refurbishing.
