Collisions sometimes not detecting

[csf30816]

I have a small game with a circle player and some polygons and circles around (~1.1k colliders). Once and a while I will find that a collision is not detected between the player and an object. I don't know why this is happening as I use a class to create the objects and other objects collisions work perfectly. I don't think it's because I passed some mystical object limitation number, because objects created after the broken ones work fine.

I am using counter clock-wise polygons. Created like this:

var poly=new Polygon(x, y, ...);

system.insert(poly);

I know this repo is pretty dead but maybe someone faced a similar issue and can help. Thanks.
