I have been getting this issue on the movement phase, the unit display and done button are not displaying correctly.

if i hide the unit display, it shows correctly once i show the unit display again. also works fine if I reload the autosave.

this seems to be something with html text in a label, it happening to the summary tab, sensor info on extra tab, and done buttons. all these use html text

I was going to be working on 49.13 this weekend. Would you consider this a blocker for release?

it is annoying, but you can work around it. think i may have gotten the IllegalArgumentException with 0.49.12 also, but not the display issues

As a note for replicating this issue - set the skin to "plainSkin.xml". I haven't been able to replicate in other skin settings with respect to the done and skip buttons.
