Do you have a town? Taxes may be a reason for the loss of 300k and if you got kicked for inactivity in your town, that may give you the answer to where your stuff went.

The only town i am in is Dax and that only has 1 monthly 5000 tax. Even then for 3 months, 30 days * 3 = 90 and 300,000 / 90 = 3,333 so that means a town would have to have a daily tax of 3,333 meebles. And then Explain why my God tools, weapons and Armour are gone.
