Hi Galagaking and Batilan
Thanks a lot for using the app and uploading data. It looks great on the map!
Galagaking, unfortunately I broke something server side with the uploading of data. And I only realised when my own measurements did not show up on the map today. Luckily I also logged to a file and was able to import the data afterwards. The bug is now fixed (reverted code server side, but also updated the Android app) and everything should work fine again.
Please send me the logs and I'll import them on ttnmapper.org
Regarding the "good measurements" at the wrong location due to a gateway moving, I am working on changing the database queries to ignore measurements taken before the last time a gateway was moved. When this is implemented the "wrong data" will disappear from the map.
