There will be an "Always On" options next Patch.

Minions/Defences which are not on full health should ALWAYS show their shield, so there should not be an issue to keep health up as all damaged units will show their shield permanently until recovered.

However if someone wants to see the units current XP Level permanently it could make sense.

We are looking into that.

The new Patch is now out for a week.
Did it improve the situation for you?

Declining for now due to inactivity.

Not really as this is a very strange case and we yet have no pointers what is causing this.
But surely it can not be related to our code and since we updated Unity3d and CoherentUI to newest versions it might have helped, yet it should not trigger a sudden reboot no matter what.
We found recently a memory leak in Unity3d when loading from scene to scene which seems to be fixed in newest Beta (which we will update to once out of Beta), but I not sure if it could be related anyhow.
However did you play all 4 levels in one go and have you checked if you get unusually high RAM usages before the game reboots?

This sounds hilarious and interesting!
But glad you found a work around :)

Does it work now correctly with the new Patch?

It could well be as components fail in a way I have never seen before:
"[Coherent Browser] (Warning) View 0 terminated in an abnormal fashion!"
(from your first log)

Or the game crashes totally unexpected points at trivial things eg.
"0x00007FF7768F53DD (WFTOGame) RectT<float>::GetCenterPos"
(from your second log)

But this looks like you could have some memory corruption.
Do you overclock your memory?

Thanks for pointing this out :)
