Hey. Here is fine too. So up till now, in principle the world of Fugl is infinite, but it has a start which is what you see is in that picture and then if you fly faster than the world can generate, then you can also make it till the end. Try to fly, keeping the sun on the left, and the biomes will slowly change.
However, for a couple of reasons, we are now changing that around. So soon each biome will be contained and you have to go to the menu to change to a new one, and we are now slowly phasing that in. That will eliminate all border bugs like in your screenshot. As part of that switch over, we have temporarily disabled the procgen completely. So there is a beginning and an end. The end is quite far down though.
Hopefully the new version will land soon. Thank you so much, for playing this and taking the time to post these bugs.
