Implicit assumption of colony ID column name in bumbl()

#this works:
bumbl(bombus, t = week, mass ~ week)
#> # A tibble: 1 x 6
#>   colony   tau logN0 logLam   decay logNmax

#> 1 NA      6.20  7.52 0.0170 -0.0215    7.63

#but this doesn't:
bumbl(rename(bombus, colony_test = colony), t = week, mass ~ week)
#> Error: Join columns must be present in data.

I think the best way to deal with this is to just require a colony ID column. If the user wants to run bumbl() on a single colony, they just need to make a dummy column.
