Which risk increased in siege towers when Roman engineers introduced the corvus?

💡 Explanation

Catastrophic structural collapse increased because the corvus’s weight caused an elevation of tower's center of gravity, thus lowering stability; rather than improving, the stability was greatly decreased therefore making the siege towers much more dangerous.
