Changing any function to a new key will result in that function not working at all. From what i can tell, this is any key, any keybind. Only the default key will activate that function eg. Z to drop items. I have no mods, only Space Age DLC, it also happens to my friend when either me or him host the save file. This issue only presented after updating for the DLC.

Can you please give an example of a key you re-bound (what it was bound to, and what you re-bound it to) and a case where it's not working?

I have just been on to double check and it now seems i can change anything apart from "drop item" which only still works with the default of "Z", previously nothing could be changed. I would like to change drop item to one of my side mouse buttons. The bind does also not work with a normal keyboard button and using the extra mouse buttons on other functions does now also work.

Did you un-bind the other controls that are bound to those buttons? Specifically browse-back and browse-forwards are on those keys by default.
