I tried generating a mission with enemy dogs. No issues, no crashes.
Maybe the problem is with tkzv's installation? No idea.
Gentoo Linux AMD64.
I installed the nightly vanilla OpenXcom, then
unpacked the original games to ~/.local/share/openxcom/UFO/ and ~/.local/share/openxcom/TFTD/ ,
unpacked OpenXcom_XFiles_0.6.5c.zip and copied OpenXcom_XFiles/user/mods/XComFiles/ to ~/.local/share/openxcom/mods/ ,
umpacked Extended+-3.8a-80622cd-2017-06-13-jessie-x86_64.7z and run OpenXcomEx.
And I've got another bug to report. When a bullet destroys a staircase section, it becomes a water cooler
To reproduce:
Load the attached "for cooler.sav". — Agent "Kamran Rezaei" should be active. 2 disciples of Dagon are visible.
Switch "Kamran Rezaei" to snap shots and shoot the staircase right behind the 1st enemy. — See "before.png"
This may take around 5 reloads, but eventually the bullet hits the staircase and turns it into a cooler. — See "cooler.sav" and "after.png".
