I had to restart my vault because everyone in my vault was falling prey to radiation for some inexplicable reason.

However, when I restarted, I became frustrated because I placed an energy room next to another energy room to merge them, and they simply did not merge.

This would be easier to handle however, if there was an undo button, or a "move room" button that might have a chance of fixing the error.

On a side note, it would save a lot of time, if the customer support lead directly to the forum page to post, rather than sending a useless email that would tell me to go to the forum instead and not directly solving the issue.

Thank you

Stupid question, but happened to me before I figured it out... are your two rooms at the same upgrade level?. I was scratching my head over this when it happened, and the problemas was exactly thay... I upgraded one of the rooms then, some time after, I built another one next to it. They only merged after I upgraded the second one to the same level.

An easy way to find if this is your issue: check if the rooms have the same names, since they change after every upgrade (like Cafeteria (tier 1) > Dinner (tier 2) > Restaurant (tier 3) or so - don't know the exact names- for Food production rooms)

If you water bar ever drops into the red, your dwellers will pick up radiation. So far, that's the only thing that's done that to me.
