Confirmation

Can confirm. Lag spikes start happening on breaking or placing blocks after /filling a large amount of blocks. Just to be sure, loading new chunks (via /tp) and then breaking or placing blocks doesn't produce lag spikes.

Condition resolves after quitting/reloading world without quitting Minecraft. Condition doesn't resolve after reloading chunks (F3+A)

Log produces similar output to OP. Lag spike detector doesn't trigger before using the /fill command.
