I managed to track down the one mod that was messing with lags spikes my modpack and it appeared to be yours :

Here is a spark sample of a lag spike caused precisely by tcb.spiderstpo.common.entity.movement.BetterSpiderPathNavigator.tick()

Also your mod is amazing I'm pretty sure you don't come here anymore to read issues so I might post this for nothing, still I love your work have a great day if you ever come around here 👍
