Assume there are issues.  Keep watching here to see what pops up, eventually gets solved (we hope), but wait unless you need to file early (all I can think of is a terminated entity)

There is a known issue when transferring Form 1065 to TY18: Not Enough Memory, this information has been reported to engineering.  You can try opening each return individually and saving to create the HomeBase record as a workaround, but my advice would be to allow time for an update to occur resolving this if you have alot of Partnership Clients.
