Fatal error on running Conflict Solver

[driagledd]

Describe the bug
After updating Irony I ran the Conflict Solver and it hit a fatal error on step 5.

To Reproduce
Steps to reproduce the behavior:

1. Update to/unpack newest version of Irony
2. Run Irony
3. Run Conflict Solver (any mode)

Logs
https://pastebin.com/YMnuStzt

Version:

• OS: Windows
• Irony Version 1.26.231 (portable)

Additional context
This error doesn't happen when I switch back to the previous Irony version. It does still happen when I unpack the newest version from scratch (rather than just updating).
The mod it mentions in the log (Machines & Robot Expansion Continued) has not updated since the last time I used Irony.

Latest update should fix.
