In my current PBEM I have noticed a strange occurance more than a few times with my CV TFs. For kb I usually create three Air TF and split my CVs into the three and set two of them to follow the slowest so they are in one big group. For example it usually looks like this:
White ( Slow 7:4): CV, CV, CVL, CVL, CVL....
Black (Medium 8:4): CV, CV, CV, CV......
Silver (Fast 9:4): CV, CV, CV, CV.....
Black and Silver both set to follow White. In previous games this has worked great for me. However, in this game I notice that the group travels fine for a few turns (maybe a week in game time) but then all of a sudden the whole group stalls and moves one hex at a time per phase and when I look at the individual TF they inviariably have one to three ships with maxed out Ops points (usually a CV and BB). The only way I can get them to move when they get like this is to break up the triad and send them off on their own (which presents a different problem since I don't feel comfortable having each one out there alone, must have assured combined CAP)
I always set "no refuel" and "no retire", so they should not be refueling unless I have them hook up with the replenish TF and do it manually so where am I getting these Ops points? Why are they restricted to just a few ships? So far I have not suffered any disasters from this but it freaks me out because I never know when the kb is just going to stall out.
Likely I am missing something obvious, please clue me in.
