My Meth Lab producing very slow.

[GrimReApErZZZz]

I have a fully upgraded Meth Lab and it's producing very slow. It's in Grand Senora Desert. 2 bars of supplies only produced half bar of Meth which is worth around 29k. This means 5 bars of supplies produces 75k which is literally equal to the cost of supplies. Now i've been playing this game for 8 years and i'm pretty damn sure Meth production is not that slow. Even my Counterfeit Cash Factory produces way more money than Meth lol. How can i solve this problem?

Restart your game ?
Try to change lobby to actualize.
Check you have prod and staff upgrades.

those businesses are known to be extremely slow anyways and useless, buy a nightclub and buy technicians to assign them to make money off ur other slow businesses without interfering with them, i dnt reccomend meth lab or counterfeit cash, try the acid lab its only 1 mil after upgrades and makes around 90k an hour

Same issue, so it's not just you. I've got at least 12 hrs. of playtime in with supplies available but only 2 bars of product created in that time... despite what everyone will tell you, that can't be normal. I am about to agree after wasting so much time on this business tho, I really don't think it's worth restocking and selling product at the MC business, unless you stock them strictly from knocking over stash houses. As mentioned by many other users, I'm planning to just use the MC properties to stock my Nightclub and pretty much ignore them otherwise.

mc businesses were on double cash last week so it is possible that R* ♥♥♥♥♥♥ something up during the transition and mc businesses were always a buggy mess

maybe bug or silence nerf
coke should produce full stock in 5h and meth in 6h

raid timer without security are 3 and 4h or 6 and 8h with upgrade and there are now these lovely ghost raid without any notification you might miss them completely depending on your gameplay, but you can check your business and see if it got reseted

nice bug overview from 2017

most of the stuff which is at the disadvantage of the player won't be fixed, but how dare some way is found to speed up the process
