Server Loading Screen not Working

Yeah, I know I’m pretty late to ask this, but I got on facepunch for some other stuff and realized you guys are probably the best people to ask. A recent Garrysmod update appears to broken (or changed) the custom loading screen feature for servers. Anyone know how you now use a custom loading screen?

Yeah, I know garry said he “fixed” it but it still shows up as a white screen with my loading screen and likes to crash around 50% of the time.

I even have a dump of a crash that happens as soon as I open up a panel with an html panel on it.

Thanks for the feedback!

Wait for Garry’s Mod 13. It most likely won’t be fixed in GM12.
