The update fixed placing a proxy on an existing interface, but the network is not updated upon breaking the proxy. I might suggest changing the network update call to when a proxy is placed or destroyed instead of changing proxy target. I believe that would solve #12 as well as this. Hopefully the fix is adding the 3 lines of code from #12 to when proxy is placed and broken.

Workaround is to update the network with a cable.

I was able to reproduce #12 in 1.16, but unable to currently reproduce this issue.

Thank for reporting, sorry for being late

No need to apologize at all. Sorry I keep postings more issues. I just saw the update and couldn't stop myself. You're making great progress.

I couldn't stop make this mod better with you as well!

😄

Still working on fix this in 1.16 though

I'm guessing Dynamic networks function and update differently in 1.16 compared to 1.12?
