[Shinasincell]

I dont now what was going on, but whenever I edit techtree-requirements or techtree-Upgrades Used field and select "Add" or "edit", It crash the World Editor.
I try a new fresh clean map and this not happen; It only happen in my map
Sorry for bad english

Just for my perspective these are the possibilities why might be reason why your world editor crashes.
1. Your map might be corrupted. I think most world editor crashes is because of faulty models or corrupted icons which makes a map corrupted.
2. Your World Editor might be the problem here. Though not sure what kind of problem it might be, but i still think it connects to the WE.
