Sorry, My English is bad
I hope someone to fix Windows Address

Should hopefully work, untested.

Hello Silvers, I received the following logs unable to work
[SM] Plugin encountered error 25: Call was aborted
[SM] Native "SetFailState" reported: Couldn't find the 'OnWindupFinished_Sig' address

The whole offset checking and offsets need updating too, from looking at looks like they are forcing the eyeangle check for the tank.

Can just force jump on win i think there is no docs on what it's doing so can only guess from looking at the asm.

74 20                                         jz      short loc_1034CCCE
to
EB 20                                         jz      short loc_1034CCCE

Linux is different not quite sure whats happening there since offsets maybe outdated.


Here is sig for windows and updated offset for what i think should be correct the plugin byte checking and patching needs to be changed in opinion for windows.

[SM] Native "LoadFromAddress" reported: Invalid address 0xbc is pointing to reserved memory.
can help plugin to be changed in support for windows ? I don't know how to do.

New signature and patch offset, untested but should be working.

Thank you Silver, would test if got time!

Thank you Silver.
New gamedata,work correctly.
