Hey,
back in 0.16, this mod also let the special trees from Angel's bio processing mod https://mods.factorio.com/mods/Arch666Angel/angelsbioprocessing multiply, which is a fairly large balance breaker, as they are supposed to be rare resources you harvest and use to build special production buildings. Think explore, find special mother tree, take it, use it to build special tree farm with high wood output.
Would you be open to blacklist the trees/plants from this mod from growth? Right now it is in alpha still and not ported to 0.17 yet, but I thought it doesn't hurt to ask already :).
