here's what i think happened. the reason why those items appear as it is on your characters now is because you patched forsaken RO with another servers patches. Or you patched forsaken RO in an already existsing RO folder.
it is a glitch, and just so u don't get the same problems i suggest that you reinstall sakray on a different folder then patch only the forsaken files.
this problem is a client side problem and not a server side problem.
you see servers have item codes that could be editted via the client but that won't take affect on any of the items on the server. hence, when a server sends a code for a knife for example the client could read it as a different item like a card. then again you wont be able to use that certain item as a card since the server reads it still as a knife.
in your case you are reading the bow as a 4 slotted bow when in the server it's really unslotted. same thing with the card, you reading the card as something that will add +10 to all stats when in the server its probably one of those useless cards that some private server edits to make use of it. this happens when private servers choose to edit some items in the server files but also want the clients to read it the way they editted it. the problem now is you probably have the wrong patch working on the wrong server. hope this makes it clear ^__^
once again i suggest you re install ^__^
