Tile Simplification and data not showing

[rebrancher]

Hello - I have added a geoJson of a subway line on to my map. At zooms, 11, 12, 13, and finally 14, various parts of the subway line appear and disappear. Please see pictures below

zoom 11

zoom 12

zoom 13

zoom 14

I am having trouble figuring out what it would be. I have checked my style sheet but still think that it might be related to tilemaker. Could this have to do with the "simplification" parameter?

EDIT: added config

Could you post the .geojson file somewhere?

I found the data here - if you need me to post it I can do that as well

It started working somehow - I believe that this was actually an issue with my tileserver-gl
