Make underwater labs have fixed generation or guaranteed red card room#31622

Underwater labs now has only 1 lab spawning and it’s not guaranteed that there’ll be a red card room. Making sure a red card room spawns won’t leave the relevancy of labs up to RNG.

This is an obvious improvement, and should’ve happened the day they changed from 3 labs to 1.
I think 2 labs would be a good compromise, one big & one small, but a red card room is a must to make the labs worth using!
