Enemy AI popups shown to player

[Zumwalt_446]

This issue is a tough one to replicate, but it seems to occur when the player happens to be mousing over a visible enemy unit when its AI executes a transition (withdraw, relocation, etc.). In these cases, the AI's internal processing information (e.g. "[unit name] must relocate 500m after receiving fire") becomes visible to the player; this includes the exact unit designation as well as other information. This is presumably not intended to occur and should be fixed.
