Runtime error "pure virtual function call"

[TradeMark]

I was playing map Pemsterland-Beta.sd7 with mod AA2.11, after 10 mins or so, spring suddenly crashed and i got that popup.

Thanks, but unfortunately this is kindof useless right now. In the next version the crash reporter is fixed so actual crash reports can be send again..

Fuck, i got this again.

With mod E&E0.163 in map Industrial_Mountain-v08.sd7

Anyone know the reason for this error? never happened to me before than today.
