Spitfire Mk 1 roll rate nerfed?

In Sim I was flying the Mk1 recently and I’ve noticed its roll rate is considerably slower than it was before, in fact is has been nerfed to ludicrous levels.

A full rotation without rudder now takes roughly 9 seconds at 240mph.
A 109E which was said to have a similar roll rate to the Mk1 can do a full rotation in roughly 4.5 seconds.

To show how terrible this is a Firebrand at 240mph also takes roughly 9 seconds.

Surely this can’t be intentional?
