Well that's... bizarre! At least I'm not going completely mad and I did set it up right....
Edit :
Interestingly, there is a certain similarity in the links to those two pages - taking the http part of the link out, they look like this :
stratics.com/threads/looking-for-a-magic-door.220/
stratics.com/ams/dev-meet-and-greet-europa-june-28th-2016.220/
Tapatalk seems to be getting that last 220, and the initial stratics.com, but garbling the part inbetween...
I'll pass this on to the admins so they can think about what's happening here ...
Edit 2 : Seems it used to be a 'known issue' on Tapatalk, but is supposedly fixed... maybe the version you guys are running is slightly outdated, or else Tapatalk need alerting that it's not as fixed as they thought it was?
