Q3map2-light/shadows error with -meta option cause black sha

[camel]

Hi, I got a nasty problem with lightning that causes black shadows on floors surfaces and walls on some places, some of the textures are totally black even when lighted, some have weird shadows [watch screenshots]

This happening only when compiling with -meta or without -vis

But unfortunelly I need to use both option, -vis needs to be ofc, without it you got fps losses cuz whole map is draw at once and without -meta I get error about some verts limits excedded 2800 > 1000 smth like that but only when I try to look on complex ASE model, that needs to be like that I cant change it, cuz it would look horrible with less subdivides.

I hope someone would know what is the problem, btw when I am manipulating with some of the brushes on the map those shadows are changing, so i think some of the brushes can affect that, i am using gtk radiant 1.1.1 with grid 0.025 and newest compilator v2.5.17 base - FS_20g
