Works fine for me using Firefox 31, but with a draft I just created (I didn't have any drafts laying around) @platinum_plus_5 @hassylou
I suspect it might have to do with the switch to GTC on Monday 3/18 - possible that old drafts with 30 day fixed price duration are glitching in the system as ebay wants to convert them to GTC (total wild speculation)
An experiment:
Do a sell similar on a currently active fixed price listing, but save it as a new draft (It will have GTC as the duration - the only choice other than auction format). Try completing that draft. If it works, the (wild) theory about the 30day→GTC conversion causing a glitch might be correct.
Unfortunately, that doesn't help you complete existing drafts that might still have 30 day fixed price durations - have to think on that a bit, but don't think there is any workaround. eBay would have to fix it and I doubt they would - suspect they would just say start over. That's getting the cart a bit ahead of the horse though.
If the experiment doesn't work, then it may be a browser related issue (at this point trying Internet Explorer as another browser isn't valid - IE11 is having so many problems with eBay that a test of failing with "Complete Draft" is pretty meaningless.) Try Edge, Firefox or Opera or anything else.
Last thought: If someone could PM me the link to your "complete draft" I can look at it and see if there is something wrong with the URL. I wouldn't be able to do anything with the link as it doesn't go with my account, but there might be something obvious wrong with the link. You can obtain it by hovering over the "complete draft" button/link, right click, and "copy link". Should be something like:
https://bulksell.ebay.com/ws/eBayISAPI.dll?SingleList&sellingMode=SellSimilarItem&draftId=1423333666...
