Adding tags to items changes the values of tags on other items

[Zomthar]

Describe the bug When you add a tag to a piece of gear and give it a value, it changes the value for all other tags of the same name in the same manufacturer.

e.g. If you have the tag "Limited 3" on item 1, and then add the tag "Limited" to item 2, and then change the Limited value to "4", item 1's Limited tag will also have its value change to 4.

To Reproduce Steps to reproduce the behavior:

1. Create a tag with a value on a piece of gear
2. Create a new piece of gear (must be from the same manufacturer) and add the previous tag to it, but change its value.
3. Look back at the first piece of gear and its tag.
4. See error
