Glitchy Gen Walls?

[Zhihu]

Anyone else having problems with gen walls? A lot of times it tells you you cant place gen buckets here....with no explanation on to why. Then I start genning my sand walls, spend about 400k on them and they go up like 30 blocks and stop.

An admin already had to fix my obby inner wall because they stopped during a server crash but this time the server didn't even crash.

Mine were working fine a couple weeks ago, but today some people were saying it was buggy. I think walls that gen downwards work, but walls that gen up (sand and gravel) are bugged.
