Happened the same with me. I had just bought my new house; (bought it with "Nfuker") and filled it up with items; then went skilling with "Kinapoya"; attacking each other. We were skilling all afternoon and lost 2 distance levels and 4 shielding levels. While this time, i was making "exeta con" and throwing them into house too. (About 250 enchanted).
I really dont care a shit about my skills, im worried about all items i got on house;.. I decided not to play more with my knight "Xplo" so his items were on the house too. Majority of items I've lost; are items that i had 2 days ago in "Xplo" depot. Dunno if you can check it.. Some of them are: dsm, demon shield, ring of the sky, yalahar armor and legs, dwarven helmet, medusa shield, some demonic essences, noble axe, stonecutter axe, heroic axe, +200 spirit potions, and A LOT OF ITEMS TO SELL AT DJINS. (Like 10 knight armor, 30 springstrout rods, 2 full bp of dragon shield + wois; 3-4 rh)..
And I'm missing a lot of other (I HOPE) not as valuable things that were in my house. I decided not to play more at this server (had lost near everything gained since I'm playing); but I couldn't resist to come to forum to see if I was the only one (because I saw every house full of items while mine was empty)..
What a surprise, I'm not. Thank you for reading, waiting for your answer
