As I have not installed all the EP's that this mod controls for role sims, do I need them all for it to work properly? I am lacking LN, Pets and IP (I think it has IP in there as well). Sorry If I am missing some documentation where it says which EP's are necessary.

IP is not required. Afraid I can't speak from recent experience on the others, but I never thought any EPs were required to use Register. In theory the mod would just have fewer types of Role Sims to manage. I think some players without certain EPs (LN probably) have found unwanted numbers of unusable Role Sims spawning with no positions for them to land in, but I don't think it happens to everyone.

There is a bug where it spazzes out without LN. It is fixed but I haven't released it. Getting there.

Thank you both. No rush or anything, Chain. I had it in and 70 role sims spawned in less than 3 sim hours on a test save before I took it out and wasn't sure if I needed all of the EP's or not.

I may just install LN after getting over 100 error trap messages from uni "foreign visitors" attempting to visit lol
