and of course I messed up thread title... should be 1800s ... uuuggghhh
https://forums.ootpdevelopments.com/...strictly+1800s
so I downloaded the injuries.txt from the above thread & it was a 1 for 1 match with the current injuries.txt except it is old and missing the data for new body part, nagging, surgery, and the influence fields
BUT because it was, with some Duck Duck Go-ing, almost perfectly 1 for 1 I was able to get those added fields onto the 1800s verbage
Oh the file replaces injuries.txt in OOTP Baseball 18/data/database
of course rename your original injuries.txt incase something goes wrong... but this works on my box
OOTP18 is just an example will work with any modern version that needs the additional fields
to use it in a current league I think the process is Game settings Database tab then choose re-import injury database
