world() lacks highest resolution source file

[DrAuxetic]

Hi,
I noticed that when running something like geodata::world(path = paste0(orig_dir, folder), resolution = res))
when res was 2 the map was actually a higher resolution, and had more of the little islands, than when res was 1.
Looking at the files that save to my local gadm folder, the file gadm36_adm0_r1_pk.rds is 2.3 MB, the exact same as the file for when res is 3 (down to the byte) other than the r3 in its name; while the file for res = 2 is 4.3 MB.

Sorry if I'm just doing something wrong, though I couldn't figure out what. Seems to me that someone at GADM uploaded the mid-res file twice by mistake though.
