[Opensim-users] weird eye color problem

[Serendipity Seraph]

 I run a region under 0.6.9.  For some reason both of my avatars have
got weird eyes now.  For a while they looked fine.  Now both of them
have pretty much unicolor eyes, no iris.   Under appearance the iris
texture seems to be blank/white.  So I am unsure what the heck is going
on or how to fix it?   Known problem with maybe known fix? 

Thanks.
