It is expected this will be fixed in the next patch.
Daybreak is preparing a patch to fix numerous bugs. The date of the patch has not yet been announced.
UPDATE from Daybreak, December 14:
Regarding the experience loss on resurrection bug:
Due to the complexity and risk associated with this change, it is much safer to have this tested and vetted on the test server. Any change to the experience code is quite complicated and risk prone (you would not want to level up from 108 to level 1 for example) and we need to have exhaustive testing before this goes to live. The fix is being pushed to test right now and will need at least a few days to ensure that nothing else breaks. We know this delay is frustrating, but we cannot get this wrong or the impacts could potentially be way worse.
UPDATE from Game Update Notes: December 19, 2017:
- Fixed an issue where resurrection failed to return the correct amount of experience for level 109 and 110 characters.
