*Firstly and probably the most agrivating one is that i will load in and random single pieces of track are deleted. I usually dont find these pieces until heavily into a play session which causes me to miss out on lots of shapes for my operator level.
*Secondly my blueprints sometimes get deleted upon loading in as well, which is fine because i can just re-blueprint my builds but it gets annoying after a bit
*Thirdly ive noticed using the upgrade that allows you to launch a train into the vortex doesn't always accurately update/count towrds completed shapes
*Lastly ive noticed that shapes sometimes get deleted as they load into a package. The loading bar will flicker back and forth and eventually fix itself.
