Bug with TDM modpack on Gron strategy files

[Beorne]

I've playing with TDM modpack 3.60 and at one point, when a Gron was attacking (I think) appeared some error message about missing gron attack strategy files.
i'm sure I don't have messed around with the TDM dir.
Someone can help? Thanks.

Do you recall the name of the missing strategy on the error message?

It does not have reappeared anymore, I've redone the turn and the gron has asked me peace. If it happens again il'll write
Thanks.
