Who it affects: People who like convenience and prefer their equations to look pretty

How to replicate (Any OS, because both the latest and the previous OS do this):
-Turn on Stat wizards
-Press 2ND STAT, Right, 5 to go to the seq( wizard (Thanks seanlego23 for catching the error)
-Enter an expression i.e. 50(3/4)^(x-1
-It is imperative to keep that parenthesis open
-Now continue the wizard as intended (for testing the bug, I used 1,10,1)
-Navigate to and press "Paste"

You'll see that the wizard puts the rest of the arguments within the exponent. Because of the limited editing functionality, you have close the expression in the wizard and generate a new command (which takes away the time you'd save by doing the wizard).

I hope it gets fixed

On the CE, you press 2nd then STAT.

It is imperative that you close the parenthesis

Ah, I forgot. Just put it on the OP.

Not really, the exploit affects people who don't close parentheses because they don't need to. I rate this bug an "Inconsistent design principle"/10
