(resolved) Tools: Cannot change Oxygen back to Oxygen after having changed it to Carbon.

[Bletchley Park]

I get a ligand from the Compound list. It has a connecting Oxygen (NOT an Oxygen sticking out reaching for a sidechain). I change it to Carbon. I try to change it back to Oxygen and the tool won't let me.

BUG (or explain why this is not possible or suggest an easy workaround other than 'bridging it')

Thanks for the report – I can confirm that I'm seeing the same thing, and this is a bug. (You should be able to go O->C->O.)
