Hello,
The problem with Edit Chips has been fixed and you just have to wait for the next update now. The wire issue is probably caused because of how the collider for wires work. Copying and Pasting chips is a pretty unknown feature it's already in the game you can Copy, Paste groups of chips. They won't retain the connections but that may be added in a future update. The idea of having a grid system and Inputs at the top or bottom of the chips or workspace is very nice
Thanks for playing Digital Logic Sim 2. We appreciate your support!
