[5e OGL] The Ice Devil has a value of 3 in npc_con_save_flag, is this for a reason or just a typo?

My understanding is that flags are set to 0 if false and 1 if true, am I missing something? Specifically for the Ice Devil 3 of its saving throw flags are set to 3.

I do see this in the sheetworkers of the 5E OGL character sheet: // 1 = First Entry Single Digit, 2 = First Entry Double Digit, 3 = Later Entry Single Digit, // 4 = Later Entry Double Digit, 5 = Negative Bonus Not sure what that means, but it's just before the section that defines the various save_flag attributes. You may want to look at the code yourself: (<a href="https://github.com/Roll20/roll20-character-sheets/tree/master/5th%20Edition%20OGL%20by%20Roll20" rel="nofollow">https://github.com/Roll20/roll20-character-sheets/tree/master/5th%20Edition%20OGL%20by%20Roll20</a>). See line 6783.

Just needed to know if it was a typo (so just fix it manually) or come up with a work-around for flags having more than 2 values, testing a work-around now. Thanks :)
