I have been told my plugin is incompatible with EWG. There is nothing in the TreeGravity code that would prevent trees in EWG from felling, besides the "HouseProtection" config setting. If you are attempting to use TG with EWG,
set HouseProtection to 0.
To figure out what the compatibility issues were between plugins, I contacted minelazz, creator of EWG, to get a free developer copy of the EWG jar file to test both plugins on the same server. I contacted minelazz multiple times, and he has never responded to my messages. Unfortunately, until I have an EWG jar file to do testing with, I will not know what is causing the plugins to be incompatible, and so I cannot solve issues for which the cause is unknown. I am not willing to pay the $40 to test why EWG is incompatible with my plugin, as I have never used EWG and don't intend to use it on the servers I play.
The only suggestion i have is to set HouseProtection=0. If that doesn't work, you can either contact minelazz directly about allowing developers to test their plugins with EWG, or use
minelazz's treefeller built for EWG.
All future comments/questions/issues regarding Treegravity and EWG compatibility should be directed to minelazz.
