In attempt to keep all the server running smoothly, We ask that you unload all your chunks if you are moving to a different pack.
As an example, I am playing mostly on BAGEL and I am not on DONUT or BRUNCH very much. I unloaded all my chunks in DONUT and BRUNCH.
Q: Can I go back to that base once I move to a new pack A: Of course, you are free to move around
Q: If I decide to go back to a pack, can I chunk load the chunks again. A: Yes, but make sure you unload the chunk in the server you are currently not playing.
Q:Can I keep my base chunk claimed A: yes
