Bug(?) with passing to upload.farm for rendering and rate limiter

[Laukei]

Hi Henrik, I hope things are well!

I got an email from someone today who has a problem with how upload.farm handles his save. The bug involved is relatively simple to fix, but he also mentioned that

On the planner, when trying to render w/ a different season, I receive
this error:

stardew.info say: Rendering failed. Please try again in few minutes

I loaded his savefile into the planner and rendered it in a couple of different seasons, which worked fine, so I tried to figure out what the bug could be he was getting. The only thing I can think is that he might be hitting the upload.farm plan rendering API rate limiter. If a render hits the rate limiter, does it have a separate alert to the user, or does it just time out and say rendering failed? If it does this, would it be possible to give a different error when it times out, maybe mentioning that upload.farm is rate limiting and to try again later? (I hope that's not too demanding, apologies if it is...)

Cheers!
Rob

I've added separate error message when upload.farm API responds with status code 429 (rate limited).
