An other crash

[a-detiste]

I got a crash, it's not the first time (maybe second of third in hours of play); but this time I took the time to save the log. The autosave is quite usefull ! I lost almost nothing on my progess.

I can reload the autosave then got attacked by 30 fighters & 3 balista like 30 seconds later; then I loose because I was overconfident & didn't built a big enough army. So this save would be only usefull for debugging purpose.

Maybe there was an overflow somewhere when IA decide to attack with all units at once.

Thanks! Unfortunately, I couldn't find anything in the log or autosave that would shed light as to why the crash happened =/

I experienced this one too: https://github.com/Andrettin/Wyrmsun/commit/d157aa21f79b63642a4cebfa3aa86c25a7bac792

But this is fixed now

Hi again,

I've never used a debugger (even thought I had an IT bachelor 10 years from a lame school in the rust belt); so I'm just giving it a try:

This happens on a Scandinavia custom map where I start with 2 worker & 2 fighter. Crash happens when I came too close to early enemy's base and pick up a fight with enemy's 2 fighter.

Same crash happened on previous try with the tribe from the east (what looks like Finland)

Thank you, that was very helpful :)

Fixed the crash: https://github.com/Andrettin/Wyrmgus/commit/fc5d0e0b9945f166b1d0e8f3c637f4b185810362

I've released a new version (1.8.5) with the fix.
