[Bug 🐞]: MPL Refuses to send science

[slee2018-spec]

Brief description of your issue (aka the problem)

When the Mobile Processing Lab (MPL-LG-2) is patched by ODFC, science transmission appears to work (progress bar reaches 100 %, “transmission complete” message), but no science is removed from the lab and nothing is received at KSC.

Operating system

Windows 10

KSP version

KSP Version: 1.12.5.3190 (Windows x64)

Version of addon

ODFC Version: v1.2.99.0-zed'K ModuleManager: 4.2.3

Steps to reproduce the behavior or issue

Place the stock Mobile Processing Lab MPL-LG-2 on any vessel.
Process some science data inside the lab
“Transmit Science”
Wait for the progress bar to finish → transmission reports as successful.
Check the lab and R&D → science amount unchanged.

Expected behavior

Science should be deducted from the lab and the corresponding amount should appear in the KSC

Actual behavior

Progress bar completes, message says transmission finished, but zero science is deducted and zero science arrives at Kerbin.

Environment

ModuleManager 4.2.3
Heavily modded install (full mod list available in attached Player.log)
The same vessel transmits science correctly if the OnDemandFuelCells folder is removed.
