I'll post here the bugs I found in the A5 :
If you eat something which is in the toolbar by right-clicking when it is selected, you will it eat twice and its number will not decrease. It doesn't do so if you right click on the toolbar.
Very laggy (I know you said it but I tried with a 0.25km² map and it is still the same) compared to A4 and for the same settings.
The world seems overcrowded with animals, this might be causing the lag as there is so much animals to show. (I tried to mess with the generation values in the server settings but it only makes it crash.)
When I try to open the minimap, I get a few seconds of freeze, the window show up but no minimap inside.
The reflection of the water is blinking.
- The farmer table have the skin of the butcher table, on the miniature and in the world
This is what I found for now
