</div>

1. Submit a lab puzzle
2. Change a base
3. Undo change

The following error dialog appears:

Fatal error!

Failed to execute ‘setitem’ on ‘Storage’:  
Setting the value of  
‘\_\_storejs\_EternaSettings\_puz\_9148855’  
exceeded the quota.

(Actually it doesn’t seem to be fatal but something is amiss)

it couldn’t save storage on your computer to save progress on the lab.  
it probably saved 2 minutes ago so nothing to worry about, really.

it’s just a localstorage error so nothing to worry about  
or i thought so
