Mod files not working

Only slp files that my mod replaces are loaded. ive heard this is something to do with the shorter loading times for users with mods “fix” as noted in the patch notes. The work I have done so far on my mod does everything it can to leave the stock assets alone so that the game is completely familiar to players new to whatever mod/map I’m going to upload. So basically this “fix” has completely made what I’m trying to do impossible and I’m stuck sitting here wondering if this is ever going to be changed or reverted, or if all mods that rely on assets not already in the stock game, or that are attempting to keep those assets as is, are dead in the water.

So is anything going to be done about this? Are we stuck with just trying to fit everything into places where old assets used to be?
