Summary20278: Regex Pattern Changes
Description

Has something happened in the Regex Builder in the Conditions Manager.
Have always used a Regex to validate Age ie in this format: ^(1[8-9]|[2-4][0-9]|5[0-4])$

However as of today, this is failing and not validating properly. But I have found that by removing the brackets ie: ^1[8-9]|[2-4][0-9]|5[0-4]$. it does work. But I don't think this is the correct syntax.

I have attached the lss for this - its got both the correct and incorrect versions in there from question age:

Your regex has an invisible tab character after the $, so it can never match. Please remove it and keep your original version with the brackets. The version without brackets only seems to work and also accepts invalid ages like 1234 or 250.
