What would happen if I just run IV and ET alongside each other (to keep auto dev)? It doesn't crash on game start (i haven't played long so it may cause trouble later on) any idea what may be causing the freeze? The freeze happens during the "Initializing Maplogic" phase.

EDIT: It seems I missed another mod that was the culprit, I thought I had enabled them one by one but a RNW map pack was causing the problem. Which would explain why it froze during the "initializing maplogic" phase
