See the discussion thread I created for this workshop item.

UPDATE: I don't know whether revenant100 himself made the update to the map, but now, that warp-only E2A3 has the silver key. So it can be beaten.

Revenant100, can you confirm whether or not Elevator Trouble (E2AS) has the iron key in it? I tried looking around everywhere and turned on the automap cheat and checked, but it doesn't appear to be anywhere.

Awesome that worked perfectly thanks for the help.

All I've been doing is opening up my RTLX mapset file, making changes, saving, opening up my previously created Workshop Project file (the one I first created and then used to initially upload my map to the Workshop), and then pressing "Upload to Steam". This updates my current item on the Workshop rather than upload a new one. If it helps, I recommend completely restarting the game after you've made your changes to your mapset before you try to open up the Workshop Project and uploading.

I too would like to know how to properly update maps without having to re upload all the time if possible please.

So far, I found that the test map called ROTT E2A3 is the only "regular" type of level (progression, has an exit, etc.) that can't be finished without cheating. It seems they have not put in the silver key into this level, so you must use the keys or noclipping cheat.

It's a completely different level from the actual E2A3 (The Room).
