Basically threw up a bit meter on the master fader and realized my limiter wasn't working at 64 bits. Not particularly bothered, but no other plugin affected the range to that extent. See the gif below (also for the love of all that is holy I couldn't manage to add a gif here).
Win10x64, Reaper 6.45 64-bit, 64-bit install of the Fabfilter Pro-L 2.

Is anyone familiar with this issue? I haven't installed either VST2 or AAX-versions when installing the plugin.
