[F13]

(note: this thread has a generic name because i came across multiple bugs when modding sr2, and i didn't want to make multiple threads)

I've come across a lot of bugs and issues when i attempt to mod sr2.

1: when attempting to replace the tc rose outfit from gotr with a lin outfit the game ould freeze when attempting to load the outfit. i have no clue where i went wrong.

2: I wanted to create a new weapon that uses a mesh that isn't preloaded so i got the name of the mesh, it's g_peg file and it's peg file and added them to preload.tbl, the model didn't appear in-game. the mesh ended in .SMESH but in preload.tbl i wrote .smesh.

3; I added 2 new radio stations into the game, they work fine - exept when i pause the game and go to radio stations they don't have a logo or description. where do i edit this? i know it's possible as 2 new stations were added to gotr.
