    went back to unity 2018.1.9f1 as that is the last build we could find that does not have this GC leak. However, player builds crash on some androids on boot in some vulkan code on 20181.9f1, so we had to remove vulkan support from our game as well.

    As mentioned, GC Alloc is adding 80 bytes every frame...
