Yeah it seems counter intuitive for a military force to be allowed to build up during vacation mode. Allowing construction makes sense because those are instantaneous builds anyways... but being allowed to accumulate troops, which would normally require several days / weeks to build is questionable especially if you aren't being charged for them.
Some people have already deployed the vacation feature inadvertently or come back sooner than expected. I think it's important that they be allowed to check messages and complete social interactions.
I would qualify it as a "forum technical issue" and the Game Discussion / Suggestion forum does not specify that forum suggestions go there. IDC if it's moved to a better spot though.
This nation is in Vacation Mode for the next 168 turns. This nation cannot be attacked or traded with during that time.
