Since update 8.0.0.7, after the fix to enhanced eddy current being applied twice, when using a weapon with said perk and becoming amplified the effects do not activate until the player does the usual process of sprinting. The normal version of eddy current does activate as intended on becoming amplified. Please see the attached video to view this bug in action. Eddy has become one of my all time favourite traits in D2 and would love to see a fix, much appriciated
