1.) Skill While Tinkering by Boiling Oil
In a vanilla game when a Sim studies studies mechanical, they will gain tinkering but not the other way around. IE: When a Sim is tinkering on something, they won’t gain any mechanical skill points. This fixes that.
2.) Less Hydrobot Breakage by Cyjon
Hydrobots will break down FAR less often.
3.) No Engine Weenies by Cyjon
Sims won’t quit working on the restorable car if the engine blows.
4.) Tinker Mod by Midge The Tree
Every time a sim successfully tinkers with an object they’ll stave off the next time it breaks. Also has a skill version that also builds mechanical skill.
