Custom units not loading in custom maps

I recently started making a custom campaign I was working on years ago in the Original Warcraft III World Editor, but then my computer crashed, and I lost all the files.

After purchasing Warcraft III Reforged, I noticed custom models and skin for Reforged on Hive Workshop and decided to take a crack at rebuilding the custom maps. Was going great, and I was having fun, but just yesterday, all the custom units I made for the maps are not loading the files for the models. Is this a random glitch, or is Activision Blizzard just being dicks again, and did some random update that killed the custom units? Anyone had any similar issues? Advice to fix it, just point me in the right direction. Thanks.

They probably reshuffled file paths within the game files. Since 1.30, its only flat data.000 files now, without any known way to open them to see what’s inside, so who knows what changed.

It also could be the indexing issue, some of the unit IDs from raw data got renamed or something. It happened before, a lot of classic maps were crashing when reforged came out because of a prop or two were not referenced properly, and the whole map crashed as a result.
