[2022] MODJAM2020 - Is this still a good mod to use ?

No, unfortunately. If we do another Mod Jam, ownership of the mod will be passed to the community for maintenance at the end of the event. This wasn't agreed upon in advance for the 2020 version. However, many people split off their origins into stand-alone origins. You may be able to find the origin you're looking for. :)

I'm pretty sure it's hidden on the workshop unless you're already subscribed. It's left there as a tribute to the modders who invested their time and energy into making the mod, but hidden so there are less complaints about it not being updated, which is an unfortunate oversight on my part.
