The mentioned issues **do not occur** if you are admin. Admin privileges overrides something that normally causes these to happen.
If you try to enter an occupied build block:
- your build mode info panel will go blank
- your astronaut will move at "super speed"
- lighten mode will stop working
- the orientation preview for blocks will not be aligned to the entity you're in, but will be aligned to the "sector"
How to reproduce:
# get 2 clients
# enter a build block on a ship/station/planet (doesn't matter if you are admin or not)
# try to enter that occupied build block with your 2nd client, make sure that 2nd client is **not admin**!
# the 2nd client will experience all issues mentioned above
