So today was the first day I actually used the activated ability for the harvest shield and I encountered an issue.

I have both Harvest Shields and had no issues activating the first, but when I tried to activate the second it said I couldn't.

Just wanted to see if this was normal or whether I should be able to activate both? I only really bought both as I thought 2x 10% boosts on top of Aegis and T.O Heliofield would be a nice little Shield boost. If I can only have one activated at a time that is a little disappointing

Normal. You can only have each effect once. having more than one module capable of producing the same effect, just means you can use the other one while the first is still in cool down. Just like you can't apply buffs more than once even though you have multiple of the arti.

You can only have 1 activated at a time, but when the first one expires, you can activate the 2nd one right away. No need to wait for the cooldown if you have 2, which is nice.

You're gonna be a little disappointed. Only one can be activated at a time. It's the same with all other holiday modules that have activated effects.

Cheers for the replies everyone.

Kinda bummed I can't have both at once, but at least I have learned a lesson about seasonal mods and will have to keep them going in rotation.
