POSTING BUG REPORTS:
The more specific information you can give, the better. Screenshots are good. The error log (ctrl+f12) is also useful, but isn't always required depending on the nature of the bug (I don't spam the log with the ongoing status of my code because it's bad for framerates - but it's useful for actual errors).

Note about 'Enhanced Vat Learning' (the other mod for vats):
After some collaborative discussion the devs of that mod decided to change and patch for compatibility on their side. Both mods work well together and support each other in making good vatgrown pawns.


I built and tested this with a bunch of the usual suspect mods running and nothing caught on fire IRL.

Uses a couple of destructive harmony prefixes on the Pawn_AgeTracker.Notify_TickedInGrowthVat() method and the Building_GrowthVat.VatLearning property. This means the mod is probably incompatible with any other mod that relies on these being vanilla.

Otherwise it overrides the Hediffs given to vat occupants so any mod that relies on those will also be affected.

Note on crazy skill gains:
Some users have reported children aging up from babies with very high skills instantly, with this and/or other mods. I have also seen at least one report on reddit of this occurring in vanilla games, so it appears as though it is a (rare?) vanilla bug that occurs with skills and growth vats. Not sure how to reproduce it right now, as all test pawns I've grown with the mod have all been within expected ranges. If you have any extra info though, please do share.


Alien Race Framework note:
As that mod is currently under active development for Biotech compatibility things are still in flux. I currently don't handle alien races explicitly (waiting for development to settle to see what I'm dealing with and busy with other features), but any race that uses vanilla growth moments and becomes an Adult at 18 should work with no issue. Races with stranger life stages and/or growth should probably not use the enhanced learning mode, but can use the vats in vanilla mode as I've intentionally left the vanilla functionality alone as much as possible.
AFAIK as of the time of writing the 18 year old expulsion age is hardcoded in the vats and neither I nor HAR change that. Please let me know if this has changed on HAR's end and I haven't noticed or updated this message.


Add/Remove:
Safe to add and remove from existing games. Removing the mod requires using the 'Remove Mod' button at the top of the mod settings page to clean up first though. See the tooltip on the button for steps to remove and reload and what to expect.

Performance:
The mod has to hook into a bunch of places on the already performance-heavy vanilla growth vat code to do it's thing, so there will always be some hit to your framerate using this mod. I make every effort to keep that hit as low as possible, and I'm always open to suggestions on how to improve it (especially from, but not limited to, more established modders who may know any tips or tricks).

Playing without Royalty DLC:

• If you're just *turning off* Royalty, then techprints (and by extension the rest of this mod) work just as intended.
  
• If you don't have Royalty installed *at all*, you'll get an error about tags not being supported on game load - but the mod will continue to work just fine, but with no techprints.

I'll still update the mod to completely get rid of the errors mentioned (and hard Royalty requirement), but as they are not harmful and only people who don't own Royalty but also download this mod will see the errors its a low priority.
