Hello,

my turtle is not going up/down even when there is no block ofc. There is air.
There is no logs from CC either.

Seems like it's a server only issue, because as soon as I try it out on my singleplayer world it is working

Do you have moonrise optimization mod installed on your server?
Last person that reported exactly same issue has had it caused by that optimization mod on server messing with things.

There is no logs from CC either.

Please can you upload your logs! Even if there's nothing from CC in them, they include other useful info like version numbers and what other mods you have installed.

Hey! Sorry for the late reply. It really was an issue with moonrise. I removed the mod and it is all working now.
I did not have it on my singleplayer world so it didn't caused an issue there!

Thank you so much!

Glad you've got it sorted :).

Reading through the turtle movement code, I don't actually think the obstruction checks are correct. I think it got a bit messed up in the 1.13 port, and nobody noticed until now. Will have a look at fixing that (Edit: b69a44a).

For now, I have also filed a bug on the moonrise side: Tuinity/Moonrise#95.
