After wiping the server and updating the plugin today, I am having issues with old saved buildings not pasting. It pastes partial builds, hangs up, and never gives the message that a building was successfully pasted. Also can't use /undo on these builds since the process does not complete. Copying and pasting new buildings seems fine but I haven't built anything big enough where I encounter this issue to be comparable to issues old saves I've attempted. Successful pastes of old saves seem to be only of small file size, and not age dependant. It seems random which saves work and which don't so I don't notice a max filesize where it stops working, but have only had success with very small files.

Same here; partial base's pasting.

/undo doesnt work

same goes for amall and large saved files that were working fine before last update.

have to /remove admin everything

I tried to delete this thread when I didn't have an issue with it working on another server I have on a hosting service. I get the same error in the console as you did above on the one I am still having the issue with. I'm thinking it might be an issue with Application Management Portal which I have it running through, but still haven't gotten any closer to resolving it yet. Are you using any kind of program to launch and manage your server?

If you are on Linux, make sure you install libgdiplus with apt (Google on how to install that) - there is a simple command. This is required to work with signs.
