Stop out of battle regeneration

[Nirwanda]

Just what the title says: I would be very grateful if someone could help me with a snippet that would stop hrg and mrg from working out of battle. BTW, be warned that while I'm not planning to make this game commercial it would be open for donations when (if ) I post it on itch.io. So this would technically be commercial use. I'll understand if you're not confortable with that.
Thanks a lot for reading!

You can use SRD's Map Slip Damage, just leave "Default Slip Damage" at false and slip damage won't happen for states on map,
