Sad and tired

(I play in Chaos by the way, not moving because I have 8 alts, it would be too expensive XD)

I moved my 8 characters for free back when Phantom was marked as New. You can travel from any world to a "New" world for free, and it'll also be free if your original world is marked as Congested and you move to a Preferred world.

[...]If it's a house/FC issue, get all the stuff you can to a safe place and let it be. So far FC don't get "destroyed" for inactivity, I think (but master is rotated)

Be careful about assuming things like these. Inform yourself before going on a hiatus unless you're fine with losing your house or even the ownership of your FC.

If the company leader doesn't log in at all for 35 days straight, their rank will be transferred to another member according to certain characteristics like their own last login time, their rank within the FC, how long they've been in the FC... so if you and your officers all go on a hiatus, the leadership could well land on a random recruit and the GMs cannot do anything to help you in that case. You'd have to hope the "new leader" is nice and gives the leadership back instead of keeping all of your stuff, including your FC house, workshop and anything in your FC coffer, as the previous leader would be demoted to the lowest rank and unable to do anything about it.
If no one steps in the FC house for 45 days, it will be demolished. FC houses are much easier to upkeep because any FC member may reset the demo timer by stepping inside, unlike personal housing where the tenants cannot help in any way.

And don't just trust my word, either. Always double and triple check any information in more trusted sources such as wikis and official sites if you care about your house and FC.
