JCA - Hand Flares ACE3 compatibility directly included now in the "JCA - Infantry Arsenal Compat Ace3".
This one is required only if you play with the stand alone "JCA - Hand Flares".
Good game. :)

One of the most useful mods.

No issue with this, good game. :)

Could we repack this into our mechanics mod? Would you have an issue with this?

I basically added ACE3 values from ACE3 Fragmentation Framework [ace3.acemod.org] to avoid damage when throwing JCA hand flares, nothing else:

class CfgAmmo
{
class GrenadeHand;
class JCA_GrenadeAmmo_HandFlare_Base: GrenadeHand
{
ace_frag_skip=1;
ace_frag_force=0;
};
};

i don't play with JCA Hand Flares, i don't know where comes from your issue, sorry.

hey so what does this change, I still have the error with this mod which prevents me to switch grenades after I equip JCA Hand Flares using Shift+G
