I did not change anything in campaign folder or at least I'm not aware of it. What do I do now? Re-subscribing doesn't work for me, since Steam doesn't download clean mod's files again. Should I wait for next update or is there any other solution? Thanks a lot for any answer
EDIT: I'm not experiencing this bug in any other mission in this campaign
!!SOLVED!!
thanks to STUCUK on steam workshop forum, he wrote:
GetBType should only crash if its sent a unit which isn't a building (As it doesn't check its a building thats sent to it) or if you send it a unitid which is below 1 or higher than the maximum unit count.
People shouldn't need to goto own to get information, authors should have ownership of their mod on steam.
In relation to "Clean" mod files, delete the Arabian Campaign folder thats located inside the OriginalWar\mods\ folder and delete the workshop.ini from Original War's directory(workshop.ini holds the last size/crc of the mod that it copied to the mods directory so it won't copy if it hasn't changed, deleting means it will copy from the steam cache). Then goto the Steam\SteamAps\Workshop\ folder and delete the acf file which has 235320 in its name (This will force steam to re-download the mod... well all subscribed mods). You may need to restart steam.
