Modified Object from Blender has no Collision in FiveM

[chos]

Attempting to modify an existing GTA V .ydr (first time doing so tbh) using blender, I essentially just removed a bunch of the surrounding objects, then attached a couple of objects together (all from a .ydr found inside one of the methlab MLOs)

Imported it into FiveM and it seemed to work fine, all the textures were accounted for, placement worked great, etc., however, no collision?

files inside stream folder:
tr_int4_methkit_basic.ydr (the name of the object from GTA V, same name)
tr_int4_methkit_basic.ytyp (file from blender/sollumz)
tr_tuner_methlab_1.ybn (modified collision file, same situation, removed unecessary object collisions and kept the needed ones)

YTYP:
