This is a tough one I will admit...
After installing several 1.18.4 versions, I find that I am unable to see the contents of my own scripts and scripted objects. For example, the UUID of a script in inventory comes up as all zeros.
Not just in the release candidate, but also if you re-run (without installing) the released version (1.18.3)
As best as I can reproduce here are the steps:
1) Run happily with the released version
2) Install the release candidate and run until you find something that you don't like
3) Go back to running the released version - can't do much
(symptoms at this point for me is that the contents of objects don't get fetched - and if you shop, some vendors fail to show you the contents of your purchase)
4) relog has no effect
5) clearing cache has no effect
Good news is that reinstalling the released version does clear the problem. Bad news is that there is a migration issue (IMHO)
1) my main system is windoze XP. If I log in on my mac laptop, running the release version, all is happy.
2) If I log into my main system using an alt who has mod, the same bug occurs. If she logs onto my laptop, all is happy.
So (imho) it points to the system that the upgrade occurred upon, and is not related to the service
