I have just installed the Easy sign up and log in mod and the checkout without account mod.
The problem I have is that the Reward points mod is now ignoring the redeem maximum of 25% I had set up.
It will now only redeem 25p.
if I change it to 50% then it redeems 50p.

I'm not using the latest release of reward points, using version 1.13a I think.
