Same here, except I play on official PvP server 3527. Ladders are indeed broken again (they were fixed, but new big patch broke them again).
No matter what the hatch stability is (usually 70-80-90% etc.), the first ladder section in either direction gets a standard -10% stability reduction and works correctly (60-70-80% etc). ANY OTHER ladder section in the chain, gets a 0% stability number. It allows you to build them 2, 3, 4 in a chain (connecting ladder to ladder) etc, but all but the first one is 0% stability. So as soon as you log in, reset game due to crash or freeze, or server reset all of the ones with 0% stability get erased “due to instability” (all but first one).
This happens every time you build a ladder longer than 1 section. Even if the other end is sitting on a 100% stability foundation brick and they’re hugging 100% stability foundation walls.
I’ve had 30-40 of them disappear due to this, rebuilt them all, destroyed all hatches and rebuilt, etc. nothing corrects the problem.
Please fix soon.
