The latest sphere clients allocate items way up to 09999 (and possibly higher) so yeah, you need to edit all those custom duplicate items to not use numbers in the itemdef. This explains why you are getting those odd trade window layer and hitpoint messages... because itemdef 04555 is probably a wall or some other unexpected thing and the server gets default values for stuff from the *mul or *uop files if they are not defined in the script etc.

More tips on upgrading:

* Carefully check your current sphere_spells.scp against the latest script pack... there are many changes in there relating to FLAGS and other things.
* Same goes for sphere_skills.scp file.
* Carefully check the current sphere_defs.scp file... there are LOTS of changes in there, especially relating to flags.
* Also sphere_msgs.scp needs to be up to date.
* Be careful of the "static" items in your world (items with ATTR that includes 08000)... make sure they are not being deleted/lost during a world save.
