I installed MB (https://es.gta5-mods.com/tools/map-builder) and replaced the gameconfig with the gameconfig that i had before to install it (i did a complete backup before install) because my old gameconfig had a few changes for other mods. Well, the point is that the MB works good, but when i try to put out a gun for use it, this happen (the picture). I tried to play without my old gameconfig but i cant because the memory of the game explodes.
And yep, i have already this (https://es.gta5-mods.com/tools/packfile-limit-adjuster) and this (https://es.gta5-mods.com/tools/heap-limit-adjuster-600-mb-of-heap)
