Decals don't always show #1
Description
Most of the time, when joining a server with this plugin, the decals just will not show whatsoever... Sometimes rejoining the server makes them show, but more often that not, it doesn't at all. It's very inconsistent and unpredictable as to when it will work, and I'm unsure of why this is exactly... Anyhow, have you tried spawning https://developer.valvesoftware.com/wiki/Infodecal directly at the start of a map, instead of using TempEnts? Dunno if it will work, but, it's worth mentioning.
As far as I know, the Mani Admin Mod decals don't have this issue, but, for stability and simplicity reasons, I don't wish to use Mani's Admin Mod. Hopefully, this issue can be fixed sometime. I've tried figuring it out myself, with little to no luck.
