This is normal behavior with cubic chunks (and in vanilla too, you just don't see it in logs). It does give up after 1000 attempts, just like vanilla. It's just that each attempt takes a few times longer with cubic chunks. The log indicates that it finished but then you closed the game window.

Can you confirm that the world does eventually load? It can take a couple minutes the first time but it should load after some time

Also please edit your report to not use hastebin for logs as that site removes pastes after some time

The world DOES load after some time. However the game processing completely stops and it's impossible to use any console commands or even quit the server without crashing the entire client.
latest.log

I attempted closing the client and loading into the world again. there I find a completely blank world. Teleporting to 0 0 0 shows nothing except this

rendering thing..
The world seems to work fine afterwards, generates completely blank though.
