Indeed, I was able to replicate the same issue with my C14 Pro on Win 10.
And the weird thing is that it does give different flavours of messed up renders if you choose to export dry settings or with channel settings etc…
There seems to be an issue with the modulators function with Render in Place.
The C14 update really needs to come soon.
Please also go and share your views on my post about erratic zoom behaviour so it can get considered by Steinberg :
