Whilst bulk synthing, over the course of about 120 synths, I got the message that my synth was interrupted and mats/crystal were lost a total of 6 times. Others near by also had the same thing happening, in bastok markets. /blockaid did not prevent it from happening, not that i saw anyone casting anything on me, but to my knowledge the only way to interrupt is casting on someone mid synth, or be forced to zone or forced into a CS mid synth (ferry, besieged CS, etc). I don't know if this is a known bug, but I lost more to this than to breaks.
Does anyone know if this has been acknowledged by SE? 5% total loss of mats makes me want to not use any expensive ingredients until its resolved
