Simple question: How do I turn iteration counts back on?

Running rstan 2.21.1 on Ubuntu 18.04 using R 4.0.2.

Recently, I installed the rethinking package. After that, I no longer see the iteration count when running analyses that rely on rstan (either through rstan directly or using brms). This is not true for cmdstanr, which works as expected. My .RProfile file is empty and I have uninstalled rstan, StanHeaders, etc. and things still haven’t returned to usual.

My question: is there some simple step I’m missing to turn these iteration counts back on?

remotes::install_github("stan-dev/rstan", ref = "develop", subdir = "rstan/rstan")
will probably fix it

That did the trick. Thanks, Ben!
