Sessions randomly have tons of uncompiled materials

Summary

Ever since 42.00 loading in a session, and or a new private code of our map has been entirely broken, with half the maps materials not compiling for some reason, this is even applying to things we did not change, its preventing us from publishing in fear that this will apply on the live map if we publish it

Additional Notes

This is seemingly random, and just happens even on materials that are a single node of a color

It had happened to me before, I fixed it by resaving all the materials and material instances
