Reflection Probe disappears in build?!

So I'm having a game with a reflection probe, baked, that works fine in the editor, but as soon as I build it, the baked image disappears! Both in the actual apk, and in the editor.

The weird thing is that another probe i have in another area of the game (with the exact same settings except being 128x128 instead of 256x256).

This has not been an issue earlier when building to Android or in the editor, only with ios and webGL, but now it has somehow infected the rest. Anyone care to shed some light on this?
