Collapses when scored or loaded into the oven in bread and yeast doughs: what causes it?

Likely causes: Proofed too long. Proofed too warm, so it passed its peak faster than expected. What to change: Reduce the proofing time, the proofing temperature, or both. Bake at the first sign of readiness: a poke that springs back slowly rather than not at all.
