It seems the contribution counter was set wrong when migrating Wikivoyage. Its not a big thing and its probably not fixable after that long time. Look at my one: 301580 contributions. But there should be around 94000. The count on Wikivoyage/de ist right. I have 65000 edits right now, but it seems all migrated Wikivoyage wikis were set to the same count (34.563) when starting on the WMF servers. All counts, but not WV/de should be reduced by 34.563 in my case:
Other users counts look the same ( e.g. https://commons.wikimedia.org/wiki/Special:CentralAuth/RolandUnger )
But as stated above. It's been a long time and I am not sure whether you can reproduce what happend that time, but the counts look a bit weired to me.
