`ff_simulate` throwing `position` related error for MFL connection

[wadefuller]

Describe the bug There appears to be a bug with the position column when I run the ff_simulate function using an MFL connection.

Reprex 👇 some very basic source code here.

library(ffsimulator)
unh <- mfl_connect(2022, 65804)
mfl_sim <- ff_simulate(conn = unh, n_seasons = 100)

Expected behavior Expected the simulator to complete successfully. I've run this same code in the past without a hitch.

Can you upgrade the following packages to their development versions: nflreadr, ffsimulator, ffscrapr? You can use remotes::install_github(c("nflverse/nflreadr", "ffverse/ffsimulator", "ffverse/ffscrapr")) to do this
