Hey Dust
Been using your mod in A17 and am loving it.
A couple of issues re using with an existing save though.
Firstly, you can get glitching with trees growing through boulders and through garden plants causing further glitching if you attempt to remedy it.
Ground levels can glitch out as well.
Secondly, a new forest of 1 hp trees causes an unintended exploit.
All the trees are one hit away from their xp and wood bonus, reclearing a once cleared area can quickly give a large boost in both.
Lastly, a vague hypothetical.
How hard would it be to apply your textures to A15?
