Hi!

I've encountered an issue with mods that add frames (funky locomotion, framez,...)

Placing a Matter Transmitter on frames and move it allows you to connect to a reciever, the animation shows up, but stepping on it does nothing. Replacing works fine.
A Matter Reciever produces the following issue: only the original position remains in the dialing list, the new one does not appear. The position stays in the list, even if the transmitter is removed. So after a while, your list gets crowded with invalid destinations. If a transmitter was connected during movement, you still can use it and land on the original position without a reciever beeing there.

This will be fixed in 2.51

Matter Transmitters and Receivers have internal cached positional information which external block movers cannot update. This is not easy to solve unfortunatelly but for now I will leave this ticket open so that I don't forget about it if I find a solution.

I think the biggest problem is the Matter Reciever remaining in the dialing list. Maybe you could add a refresh button (or auto-refresh) to the list, so it updates the position/remove invalid targets?
Other issues can be solved with replacing the blocks.

There is currently an /rfttp cleanup console command that you can use to clean up invalid receivers. That's half of the solution :-)
