Report:
I can confirm the issue with the scopes in v1.7 is due the splash wake scopes mod.
Do not use that mod with FOTRSU 1.7. Also, after disable the mod (if you were using it), delete all your savegames from my documents (or documents)/SH4 folder. If you disable the splash mod and do not delete your savegames, the issue will persist and will cause CTD, too.
I´m comparing the sensors dat file from v1.7 and the scopes mod with S3D, searching differences.
Happy Christmas.
