Trees on Tugboat lags out server

Love the plugin. One issue we had on my server is a player put some trees on their tugboat and it caused the server to hang. The message below was spamming RCON. Any chance we could get the option to remove trees from being placed on boats to avoid this? Unfortunately I had to globally delete tugboats to fix and nuke the NM data so I don't know what tree type it was.
