What should I be looking for? The mod loads fine and states completed. No error message there. Tried removing the modlet and it the issue still remains. Seems to have broken the birds nests all together and there are none in the world any more. Did not have this issue before adding the modlet. It is not a vanilla bug so TFP will not help. The file is too long and considered a text file so will not allow me to attach here either. So, I'm guessing I will have to wipe the server and start again without the modlet since it seems to not work?
