I'm currently playing rogue with the savage land costume. My Holo-Wolverine will auto-dismiss without my command to do so. I have A-B-A tested with the X-Force Wolverine and this does not occur when the X-Force Wolverine is summoned.
I have also A-B-A tested Holo-Woverine with my Nightcrawler using his Classic Costume and Holo-Wolverine does not auto-dismiss.
