It's annoying waiting for everyone to go to bed and some people have to log off just so we can sleep. I see no reason why it shouldn't be on here like on every other server
There are ways to stop monsters rather than adding a mod that can add to the list of problems staff have
There is a trait that can allow bees to work at night. Read about it here. Server has been up for quite a while and I've not seen anyone really suggest or complain as to this situation. It's how the modpack is intended to play...it's another challenge that you have to work through in the modpack. As to your monsters problem. . .the trusted, good, old way of placing down torches will help a lot Can hit f7 to see which blocks come up with red "x" on them and make sure to light that area.
Same thing with having rain be pretty constant, but this too can be avoided with mechanics of the modpack.
Rain and day/night cycle was a motivator to give all my bees 5/5 stats and tolerant flyer and yes its a long proces but that satisfaction
I enjoy the concept of being unable to do bees during night when starting out; it forces you to build, expand your base, work on other things then resource production. Also, when you get to a certain point, which doesn't take long at all, you can get the trait for working during the night.
