Steps to reproduce: 1. https://es.wikipedia.org/wiki/Categor%C3%ADa:Boxeo_en_2014 2. Click 'Add links' 3. In the 'Link with page' dialog, enter 'enwiki' and 'Category:2014 in boxing' and click on the autosuggestion 'Category:2014 in boxing' 4. Submit by clicking 'Link with page' button. Expected results: The two categories should be linked. Actual results: Error: "An unexpected error occurred." with Details: "$number needs to be a integer" Going to the English category page and trying to link to the Spanish category has the same error. After experiencing this, I was able to link the Spanish category to Category:2013 in boxing , so this doesnt occur every time.
The same error appears when linking these two: https://es.wikipedia.org/wiki/Categor%C3%ADa:Eventos_deportivos_en_curso https://en.wikipedia.org/wiki/Category:Current_sports_events In the two cases where this happens, both categories already have a wikidata item. I havent experienced this in any scenario where zero or one of the two categories has an item already. If it is preventing linking of pages with two existing items, which definitely worked last week, it is a regression and it is a significant one as bots are routinely creating wikidata entries for Wikipedia pages that do not have any interwiki links.
I have been able to merge two items several times, and there is a slow stream of merges here https://www.wikidata.org/w/index.php?title=Special:AbuseLog&wpSearchFilter=32 Another pair that cause this error message: https://es.wikipedia.org/wiki/Categor%C3%ADa:Adventure_Time https://en.wikipedia.org/wiki/Category:Adventure_Time

This isn't a duplicate as it affects lining pages an not merging items.
