So the Donjons range indication is messed up in a funny way: Donjon range indicators are extremely inaccurate at the corners
This is a didactical example, why you should not shove a crazy amount of changes into a patch, if you don’t do testing!
You do all the programming to print the range outline, with the straight lines and the arcs, and yet you mess up the exact values.
I don’t want to pick on the particular dev who did this, it’s just with the game in general.
The simulation, the rendering, the GUI, everything suffers from that.
If you don’t do testing, make more patches with fewer changes.
Else there is no way to debug complicated things.
Good luck with the further development!
