So this is a new one for me, though a clan mate said he's seen the same thing. Tier II (slumming while I work my way up to the Ki line) last night, all bot battle. One of the red planes was "invisible" - I could see the tag for it, but not the airplane, and since it seemed to be overly fond of me I had to deal with it (post squall line, of course). It wasn't impossible to hit, but it took me valuable time I could have been capping another sector to dispatch it.
Anyone else ever encounter this?
To paraphrase an infamous spice smuggler, "I've flown from one side of the map to the other, and I've seen many things, but I've never seen anything to make me believe in an all powerful bot." Until now....
