Skill & Level System 1.1.2: your level travels with you
With Space Travel you take your level, XP and skills to every planet – even when each planet runs as its own server.
When you change planets with Space Travel, your progress comes along: from 1.1.2 level, XP, skill points and chosen skills are also kept in a shared folder of the planet group. They sync every 10 seconds, on save and when leaving the world.
Every player has their own file with a counter there, and a server only takes newer states and never overwrites a newer one. Plots and everything else in the world stay per planet. Without Space Travel nothing new happens; to level each planet separately, switch "VerbundSpeicher" off.
