I'd like a fix where the /speed perk will not disappear when going near a beacon with speed selected. if that makes sense. Its just annoying to have to retype /speed when going to the market or a town.
This would be nice, however at least to my knowledge, I do not know if this is actually possible. This is also common for other potion effects that armour or command-based effects imitate. I do agree, however that it can be a tad annoying.
This happens with all runes and beacon effects. A current solution over re-equipping your gear is to use the /clear command. Normally, running this command would clear both your inventory and effects. Here, it only clears your effects.
