So basically, I want a type of "booster" that lasts for 30 minutes, and I'm having 2 problems: 1) If the booster claiming item is a paper, the skript breaks if I stack the papers, any way to fix? If I make the "player's tool"/"player's held item" "player's tools" or "player's held items", it gives an error and if I replace the "is" with "are", it changes nothing, so how do I do this? 2) I can't get the time to work, I have no idea, honestly.. Like 30 minutes after you "claim", the variable that depicts the booster being active should be set to false, but if you "claim" it again, the time remaining of the "booster" should be extended by 30 minutes. I have no idea how to do this.. If I try, the booster never disables itself. Eg, if I set the variable {booster} to 30 minutes from now after claiming, the "%difference between {booster} and now%" never goes negative, and I can't disable it when its 0 either, I don't know why. because if I do 'while difference between {booster} and now isn't 0: *booster effects*, It never stops, and keeps on going, forever.. For now, there is no perfectly working part of the skript, since the first part is claiming, which I have problems with, and the second part, the cooldown, I have no idea how to do. Please help!

Here is it not in this box: /ho/minecraft/signal/start_cmd: line 1: 910 Killed /opt/java/17/bin/java -Xmx${SERVER_RAM} -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -DIReallyKnowWhatIAmDoingISwear -Djline.terminal=jline.UnsupportedTerminal -jar server.jar

Whenever I start my server, it ALWAYS crashes within the first 30-60 seconds of starting up. this is the error it shows: /home/minecraft/signal/start_cmd: line 1: 910 Killed /opt/java/17/bin/java -Xmx${SERVER_RAM} -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -DIReallyKnowWhatIAmDoingISwear -Djline.terminal=jline.UnsupportedTerminal -jar server.jar

It says my bukkit/paper version is 39 versions behind... how to I update it?

I want to see all the servers owner by a specific person but he won't tell the IP but he says its free-to-join and not whitelisted.
