Router GUI goes blank when the block updates

[MuteTiefling]

Describe the bug

It's easiest to notice when you insert a camo upgrade into the router. As soon as you do, all installed modules disappear. If you close the router and re-open it it all comes back.

Similarly every time the router sends power, you see the same thing.
