I had same problem with drakes morph dragon roots
also game crash if you ever want to touch the burrow system.
1- thats why I told you about the buildings
2- there is a way to have research in units with skills
cast spelll ----> set tech to level 1-2-3. remove skill add skill
- turn on player builds --- remove skill add skill, the problem is, thats a permutation, I dont dare to do it. to many triggers.
Well, I see. About the burrow thing, that isn't something I worry about, I want to make the burrowed unit always visible (If not it would be OP us fuck), so I am just using a modified Stone Form from the gargoyle, seems to be working. About the thing of upgrade units... I am not sure if i got the idea. What about putting a lot of permanent and payable (both options into the original spell) boar forms? The only trouble there would be the units that evolve into more than one unit, what makes me think... How many spells of completely morphing are available? With 3 or 4 that don't bug easily I would be fine
