The Money Cheat doesn't really work in the Game. After I add Money through the Cheat as you shown and mentioned, it adds the Money, but as soon as you "earn or spend" Money in the Game, the amount is back to the usual "in Game" amount you would have without the modded Amount - so if you cheat you have, for example, 50000000 and in Game you get the next Payment of +500, it's not 50000500 as it should show/be, it's just showing like 4775e+21 or just 2.5e+19 after spending the Money for the Massage Room. I guess this Cheat is useless because the Story is set so you need to "earn" the Money in Game to progress with certain Items you can then Build/Buy for the Hotel and pay your Staff and such.
I have cheated me Money a couple of times now during the Game, it always resets and doesn't give me any more chances to buy or Build anything for the Hotel any faster.
To fix the money cheat from this mod, go to Game folder > Game > Mod director, find file named mod.rpy
then open the file with note pad and go down to "bar value VariableValue("money", 10000000000000000)" and change that stupid big number to 50000. So that line will now be:
bar value VariableValue("money", 50000)
save it and when you use the money cheat it won't break stuff. The existing number is just too big
