Tried it earlier today for the first time. Also had problems logging in with my local character yet creating one on vault was fine - even though it was set to local chars being allowed. Eventually it allowed me after about 6 attempts, lol.
Obviously you put a good bit of work into the mod itself Ziroc, I liked the attention to detail as nothing bothers me more than mods with alot of large areas that have nothing in them. This was not the case here.
One thing I might suggest is to script chests and other containers to re-spawn their contents in after a given amount of time. I had fought some creatures that seemed to me like 'guardian monsters' but when I went to loot the stuff they were guarding it seemed someone else had beat me to it
. Then another player informed me that he was seeing the same thing - empty chests everywhere.
Just call this script from the containers' Onopen field and it should work fine.
Hey it was good to finally check out the IW mod, keep up the good work!
