DllNotFoundException: libgdiplus.so.0Not An Issue

When do "/copy NAME method building" in my test server successfully create a copy of the building and then try to paste building in my main server so do copypaste from old server directory to the new one (NAME.json file) in my main server oxide/data/copypaste then do in-game "/paste NAME" and actually starts pasting the sh*t but then stops and do not finish the paste... /undo option do not works too because its not fully pasted. Ideas? Noticed some weired stuff like if demolish object like deployable near one of the signs or the sign itself then more 3-4 signs auto breaks. Also do not have working proper signartist and my signs are with /sil image loaded. But on my main server cant use /sil because its hosted on linux and idk why but plugin SignArtist do not works. Is it possible if somehow this breaks the paste or just the signs at all with or without images, because as i mentioned they strange demolish by themselves 3-4 if destroy one or deployable near em.

Here's the error shown in the console when try to paste.  Hope it helps...

IIRC this is not related to the plugin. Try restarting your server and/or validating your files.
Strange but the same building with simplelight and targets were fine, test generators with electricity... Just removed all signs and pasted it cussessfully hmm. Its not problem to add them manualy later...
Error looks to be related to custom signs.
Thanks... Might know how to fix this... :)
I was using /copy filename and then deleting filename.json and trying to /copy filename a second time but the name has to be incremented or use a new name even though the json was deleted unless I restart the server. i.e. /copy filename2 worked fine and i renamed it filename.json afterwards.
same problem.
and when i got this error, the files are corrupted and not useable. (just a door and a window appear, not the building.)

copy paste is a great plugin. but not useable now anymore for me

Merged post

Ok, i have fixed my problem:
► Same problem for BOTH plugin Copy Paste AND SignArtist.
i just had to install libgdiplus on my linux server.

for noobs like me:
sudo apt-get install -y libgdiplus

then a server restart.
it fixed my both plugin issue.
