A simple tuning mod that will REPLACE the "Invest in Stocks" interaction on the computer. The "Invest in Stocks" interaction is usually locked behind the Investor branch of the Business career, so if you like that interaction or use it often, do NOT use this mod.
With this mod, Sims will always be able to do the group sing and wear costume interctions. Sims will also always be able to sing together by clicking on fireworks, cakes and presentpiles.
