I finally got a decent list of mods working on my PC but I don’t know if I should hold off updating my game.
I only recently started playing and but it seems like the 1.6 update previously broke a lot of mods (for example under the posts tab for Custom NPC - Riley you can see a lot of people asking for a 1.6 compatibility update). I am not sure if this update will be more or less a repeat of that.
Assuming SMAPI (the modloader) has updated for 1.6.9, this page is a pretty comprhensive list of mod compatibility with the latest SMAPI and Stardew updates.
It’ll take a few seconds to load.
I also find that it can be helpful to check community news posts for the most popular mod packs (usually on their discord), as they do a pretty good job of announcing whether the mods they shove together work yet or not.
All that said, 1.6.x type updates, where they aren’t incrementing the first or second number, usually don’t break as many things. Personally, I’d just make a backup of your entire Stardew folder before you install the 1.6.9 update (and the latest SMAPI update, and any updates for your mods) and see how it goes. SMAPI will usually warn you in the console window at startup if it sees any mods it knows have broken. If shit’s fucked, just restore your backup copy and try again in two weeks.
