make burrowers unable to burrow in the lifeboats.

As above. If they can’t in the DS I don’t see why in boats.

that look like an issue to me you can post it on github if you want.
if you don’t want to make an issue on github respond to this and i will make an issue for it.

tbh I haven’t figured how to do anything on github

If you visit www.github.com./cmss13-devs/cmss13/issues, there should be a funny new issue button.
