Hi DonQuiche,
I confirm that IGE is compatible with my mods (I use it myself, it's a wonderful debugging tool
).
The only restriction that I have noticed is that IGE must be loaded at first or it will not show up in game.
If you want to run some test here is the active link for the postmodern expansion, which requires the main mod to be loaded before it but after IGE.
The easiest solution is to use the last version of the mod : main mod and expansion are included in one mod.
I don't agree with Steam last rules for the workshop so my mods are available only from CivFanatics now.
