when you drag material which have more than 1 to collection it look like you didnt lose any material until you update your inventory again.
such as
- if you have 1 lizardbone drag and drop to collection it will disappear from your inventory
- if you have 3 lizardbone then drag and drop it into collection
- inventory still say you have 3 lizardbone
- actually you have 2 now
- just close and open wont work it still say you have 3
- took awhile for it to update to 2 dont sure what the condition is
