[1.0] Maneuver_Scratch_MeleeHit InvalidCastException (Any Wildlife)

[jecrell]

Firstly, I will say I did try to log into Mantis to see if this was a known issue, but I could not for whatever reason.

What the circumstances were.
- Started a new game using the RimWorld Unstable Build 1.0.1936
- Played for several days until wildlife began predator routines.

What happened.
- Wildlife preyed on each other as expected (red fox eats a rat).
- During autosave, red error messages appeared, disrupting the game flow.
- Saves further create more errors when loaded.

What you expected to happen.
- No error messages expected.

Steps we can follow to make the bug appear on our machine.
- Load this save file ( https://drive.google.com/file/d/1tlEY5PGxNEtM09RceEP4qgckXygEN0-M/view?usp=sharing )
- Wait for autosave or try to save
- Receive errors.

Yup. Got the same error. Surprised it even compiled tbh.

[Mitz]

mantis says it's "fixed", my apologies but i have a brand new game that was newly updated and yet i still get this. this isn't fixed.
updated @ ~9:30AM EST, today, ~1 hour ago. ZorbaTHut says it is "fixed".

[Audorn]

I just updated to 1.0 and started a new game a few minutes ago and had the same exact problem when the game autosaved, but with Maneuver_Bite_MeleeHit, between a fox and a squirrel.  There were no successful scratches in the fight.

On Mantis, I found 0003436 Exception while saving Maneuver_Smash_MeleeHit, which was marked as resolved today, but no Scratch or Bite.

Edit: A couple days, and a couple wildlife fights later, Maneuver_Poke_MeleeHit and Maneuver_Smash_MeleeHit are all throwing this error.  If it matters - The log file was in the RimWorldWin_Data, not RimWorldWin64_Data for me, so it looks like I'm running the x86 version?

The savefile is no longer causing errors, so it looks like it's fixed. Thanks for reporting.
