conjuring multiple blocks does not work on server but does in single

ray139

I am trying to use a spell that creates a conjured bloc under my feet that lasts 5 seconds(100 ticks).(slotted in pants so it keeps casting)
when I test it in single player it works perfectly fine, but when I go on my server and try t use it there it breaks.
When the spell tries to conjure the 2nd block I get stuck in the air and the block wont conjure.
has this to do with the server tickspeed? or the way how psi conjures the block?

It's likely to do with the lag between the client and server. The client handles where the player moves, and the server handles where the blocks spawn, so there's a (very difficult to solve) slight desync between them there. I have only ever written spells on servers, so I'm used to having to cast my bridges one or two blocks in front of my feet so that the server has time to tell my client that the next block is ready before I try to step on it and fall to my doom.
