1: the tremorsaurus bugs out when the raygun is used it just goes animation crazy
2: I have never been able to see a amber monolith spawn creatures even if I wait a while it might be a bug
3: sometimes in the primordial caves you cant move or even change the direction you are looking without ambersol rays glitching
this last is a question are you guys planning to ever add the creature from the mystery cave painting

If you are in creative, can you run the command "/data get block ~ ~ ~" replace the ~'s with the coordinates of the amber monoliths, it'll show you the next time it will spawn.

I'm having the same issue, it shows it won't spawn for 29000 ticks, or 25 minutes.

If I recall, you can change the amount of ticks it takes for an amber monolith to spawn new mobs, the default time it takes a monolith to spawn is not really an issue.
