From wiki, my bad for not researching first:

"Shard 3

Launched in November 2018, Shard 3 was billed as a 'non-subscription' shard. All players on this shard are limited to a max of 20 CPU (regardless of GCL/Sub/unlock status), which slightly evens the playing field for older players vs new ones. This shard again had a 60 day cooldown where travelers could not come from other shards, you could only respawn or spawn onto the shard."

Hi,

I recently purchased CPU unlock, which put my CPU limit to 50. I'm using right now about 25-30 CPU. Despite being below limit, my bucket is constantly draining. Is it an intentional mechanic?
