Strange Ship Movement in Tact Combat

[Grand Deceiver]

Last night while conducting offensive operations against another empire I had some very strange things happen.

Several (8) small fleets with an average of (11) vessels each had just entered into Tactical Combat Operations (TCO) with the express purpose of liberating a planet.

A majority of the vessels were Frigates with a normal movement of (5) in TCO.

A full 75% of all vessels involved showed only a movement of (2)..(which is not the norm as stated above).

These vessels were not damaged..and had entered the sector with plenty of Supplies and Strategic Movement (consequently..these same vessels and fleets had conducted TCO a few turns earlier with no degredation of effectivness).

Also....even tho the Targeting % was showing a (99) to attack the planet...the vessels with reduced movement would not engage the planet (I have checked the strategies and could find nothing to preclude them from engaging..plus it was Tactical combat..so I had MY finger on the trigger..not the AI)

Has anyone else ran into this?

I was playing the AI Campaign..so I will post in that thread also.
