Need help with tweaking Diablo 3 Classes mod

So I’m trying to tweak the mod to add more skill points per level, max devotion points.

At first I was adding the neccesary playerlevel.dbr, editing it and building the mod.

Mod was working only partially - I was getting the increased amount of skill points BUT the UI was messed up. Asset Manager was showing errors related to UI of custom masteries. SO after digging for a while I found out that I need the custom template. Found the template, placed it where it belongs and next mod build showed no errors.

Now in-game UI is fine, i get the increased skill points. I’m making Necromancer character. Now the new issue is - when I cast Raise Skeletons skill it only renders partially. There’s first animation on the ground but the skeleton itself is invisible and apperently stays in the place of casting (when monsters aproach the place they start getting hits from the invisible skeleton)

What do I do wrong when building the mod?
(I read modding tutorials here, know how to use Asset Manager, extract ARZ and ARC files etc)

p.s. it’s for personal use only.
