Memory leak when use yojimbo

[nongvantinh]

Test yojimbo.zip

I used Yojimbo with the Godot engine mono 3.3.2, and it seems that C# version doesn't work well as C++.
After the packet was sent, memory somehow doesn't return to computer, and object still live when program is running, and result with memory leak.

Step to reproduce:
Press build button in the top right corner.
Inside Main scene, click Spatial node and uncheck ServerBuild.
Export client by: Project -> Export -> Add preset -> export.
Return to the editor and check ServerBuild and run server.
Now run client build.

Keep pressing c or i or s keys. You see message never deleted.
