The plan has always been to slipstream my custom files into the base RPG download and then make a seperate pack for those already having TRPG. After custom models are received, I'll wait 1-3 months to allow for a buildup of newbs that possess the slipstreamed pack if I ever do anything with it.
I know. I've seen servers all die out from custom prefabs. The thing I was counting on was the fact that I host the primary download for TRPG. I won't change the TRPG files at all, I'll just add extra support for my mod.
