So, gradually over the course of a month or so more and more props have been becoming errors for me.
In attempts to fix this ive remounted content, cleared my cache, deleted my lua, verified game files, factory reset my Gmod, cleared addons and deleted them manually.
Upon doing all this my chatbox now looks like the old one from 2020 and earlier. No errors have been resolved and are still missing. Now my chatbox also has missing textures.
I suppose i would likely aim this at the Dev team @Xaze @Baron @Guac
