This error is getting god awful annoying in the new interface. It wasn't nearly as bad in the old one, but now even adding just one to the offer doesn't fix the issue. I add 2 and then I have to edit each year to match the 5%. If I'm using the slider to determine salary this shouldn't be an issue.

I didn't realize this was still an issue, I did release a patch for it a while ago. I'll look at it again.

It seems to be more of an issue when offering free agents near the max amount.
