More Awesome Than You!

At the moment I use a single PT replacement hack (the default sim gets replaced, that's it) but I'm looking into getting a multi-PT hack.

A warning I'm seeing on nearly all multi-PT hacks is never to remove the sim files if you install a new multi-PT, as this messes up the genetics in the game and leads to borked fambly tree business. However, my single PT hack has no seperate sim file that I could leave in the game if I would switch to a multi-PT hack. Would switching mess up my game because it cannot link to the single PT replacement, or should I be fine as it would just link back to the original Maxis PT?

I don't know whether removing your PT replacement would mess up your game, but I am pretty sure that not removing it when you install the multi-PT hack won't cause any problems or conflicts, at least it if really is just a default replacement.  AIUI, multi-PT hacks override the code the chooses the sim to be the alien father, and don't actually do anything to the original PT's data - they just make it so that that data never gets used.  If your PT replacement just overrides the data, it will just be ignored by the multi-PT hack the same way the original PT's data would be.  Probably won't hurt to run HCDU anyway, though, and you should probably verify with the creator of hack in any case.

Ah great, I'll just leave mine in then to be on the safe side. Baa, Rufio!

Sorry lol, but what is "PT".  I have been trying to work it out since yesterday but I give up :D

I think it might be Pollination Technician.  At least that's what I worked out, as there were multi Pollination technician hacks/mods designed to mix the genetics of Alien babies to counter every alien having the same father figure.  But it could mean something else.

It is Pollination Technician.
