I am having issues w/ TTS where maneuver dials don't show up and the delete key doesn't work to remove objects. These are issues I've had with at least two factions but my opponent does not have these issues.

Has anyone else experienced this? What was your solution?

Could the things you were trying to delete be locked? In that case you need to hover the mouse over them and press L first, before they can be deleted.

Dunno about dials, could be a bug, or you might not be setting it up correctly. Read the guide maybe?
