multilookup field provision detaches lookup list

description

hello!
1st may i say i'm a great fan of the geneses lib!

we use it alot in our company and there is a bug that's repeating itself all over the projects, and that is when you re-provision a SPFieldLookup with AllowMultipleValues = true and SPFieldLookupValueCollection all the lookups in all the lists that has this lookupfield cannot find any values anymore, like in img1.png.

the funny thing is that there is some trick, if we go to the columns definition (/_layouts/15/FldEditEx.aspx?field=internalName) and uncheck the AllowMultipleValues , save, go again and check AllowMultipleValues, save, suddenly the lookup works fine except losing multiple values.

thx alot
ariel
