After playing against this overpowered race with Lord Chris, the game begun to get better when I was making a comeback and then it(game) crashed. Chris thought it might be the demon archer, in which I checked and the unit appeared stable. However, after playing against the AI with a modified Creon pack race, the game would always crash in the Demon's base. I noticed it was 4 buildings. Those buildings being the pit, summoning circle, and the 2 gates. After checking those buildings, I found it to be the side gate whereas the script for the gate was a TA side gate and not TAK. With a few adjustments to the script and verifing this was the crash, Demons appear stable and a decent race albeit overpowered.
