Infinity Plumber crashing in 1.2.5, not in 1.2.3

Verification Build: Release_547645
Summary:
During regular play of Infinity Plumber the map will crash. Usually while digging and collecting sewage.

Impact:
This directly impacts the core mechanic of Infinity Plumber, and in fact Minecraft in general, where it is a requirement that the player digs and collects blocks. This crash was NOT occurring in 1.2.3 but started showing up in 1.2.5 despite no changes to the code. I am unable to resolve the issue as the debug log does not show clearly what is causing the issue and I am unable adjust anything in the map because it could be any of the many systems within it. Again, it was not occurring in 1.2.3

Reproduce:
1. Open up Infinity Plumber (world in slack)
2. Play regularly

Observed Result: Usually it will crash before the tutorial is complete, but it may take longer. The issue seems to exacerbate when in multiplayer but also happens in single player.
Expected Result: It not crash.
