mods.compatskills.VisibilityLock.addVisibilityLock(<skill:compatskills:technology>, "stage|tester");
It should add requirment to this skill, right? But I should reload before I will able to see this skill in skills GUI.

So let me check so I'm translating this properly.
What you're saying is that you currently have to "reload" for the skill to be able to show up in the GUI?

Sorry for my english...
I mean... I must leave and join to see skills in GUI.
/gamestage add slava_110 tester
-No technology skill in GUI-
Reopen world
-Wow, now I can see technology skill-

Gotcha, Ill look into this once I get home.
Seems to just be a sync issue in that case.
