[Fixed] Switching to Source and back deletes everything in a topic

So, I just made a new topic and tried to switch to the bb-code by pressing source.
Made my changes, switched back and all text was deleted.
First I thought the bb-code I added was a problem, but after the second try and it happened again, I figured clicking on Source and then disable source deletes all the typed text.
This seems to be pretty new, didn't happen a previously.

Cheers
Tom

Hi Tom I'm looking into why because an update was made on the forum
