You will learn that not necessarily a mod is compatible with a newer version if isn't red. the authors don't know the future, what will be in the next version.
you will also learn that usually, in 99% cases, the last line in your gamelog is the one that tells you what cause a game crash. flares are the most frequent crash cause for 1.28 so be sure you update your trucks first
Later you will learn how to open a mod and how to edit it yourself and update it. for this you will need a lot of lecture here on the forum.
for the moment it's wise you only use mods updated for 1.28, preferably Steam mods, found when you browse the workshop
cheers!
