Wear and Tear on Disbanded but Loaded Tankers?

[Anthropoid]

I loaded up a bunch of tankers and disbanded them a couple turns back. Seems like they were perfectly fine at that time. Now several of them have like 9 to 12 Sys damage, despite having sat in port for only a couple days with fuel in them. Is this wear and tear, and if so: is this realistic!?!

Like a tanker cannot fill up then just sit there at dock indefinitely without causing any sys damage!?

refits? [;)]

Helpless is right.  At the start of the scenario, the human player has to manually turn off the upgrade toggle on all the ships in a port with a repair yard or they'll dump into a refit queue.  Beware that on January 1, 1927 almost all of your US destroyers will do the same thing if they're in a port with a yard.

Hmmm, I wonder. I'll have to check that out. Thought I had turned auto upgrade off. Thanks,
