Errors when running Combat Tracker in OSE

[PXR5]

What happened?

Running combat with Combat Tracker in OSE with Group Initiative

Select Actor tokens in the Scene
Right click and Select Combat State
Errors are reported in the console
Click Begin Combat
Combat Tracker rolls initiative but typically does not select the first combatant - I manually reselect before continuing

What is the expected behaviour?

Combat Tracker should begin without errors and the first combatant should be selected by default

Sorry for the delay. We've previously investigated the problem of V10 deprecation warnings, similar to those you've pasted from the console log (#211). At least in those cases we decided that we could not appropriately address them without removing V9 support

I will still investigate the issue this week. Currently I believe it's the same as #297, a problem whose solution has eluded us for quite some time

[Rughalt]

As this refers to older combat tracker implementation, I am closing this issue.
