Hey Floggins,
Could you provide me with some screenshots of your mesh, or the triangle/poly/vert count of the mesh you are experiencing issues with?
I am sure you aren’t exceeding the count, but just for your own insight we have some mesh limitations in place for mobile devices. All mesh types can have up to 65k vertices due to the lack of 32 bit index support on mobile hardware.

If you are able to bring up the console command, there are a few console commands you could use to debug things like mesh draw count and simple stats. Try ‘stat unit’ and ‘stat scenerendering’ to get some statistics on your project.
Let me know if you have further questions.
Thanks,
