I just had a very wierd expirience on Mareth Line. I was at the mountains north of Tegaba Gap, checking out a suspicious plane engine sound (pretty similar to the one when the Storch starts its engine). I looked around but there was no trace of the plane. My guess is that it was a bugged Storch wreck, since shortly after I saw the harmless explosion that happens when wrecks disappear.
I guess it's not really a map bug, but I thought it would do no harm to post this here.
