Issue description

Using the ship helm to assemble a ship crashes the game.
Here is what the minecraft launcher gave as a crash report:
" The game crashed: exception in server tick loop
Error: java.lang.NoSuchMethodError: 'org.valkyrienskies.core.api.ships.ServerShip org.valkyrienskies.mod.common.assembly.ShipAssembler.assembleToShip$default(org.valkyrienskies.mod.common.assembly.ShipAssembler, net.minecraft.world.level.Level, java.util.List, boolean, double, boolean, int, java.lang.Object)' "
(sorry if its low quality or I missed something. this is my first bug report)

Issue reproduction

If you try to assemble a ship of any size, the game crashes. I've only tested it with the oak, spruce, and birch helms, but I assume it crashes with every type of helm as well.

Im having the same issue. downgrading Valkyrien Skies from v2.4.7 to v2.4.6 seems to have fixed it.

[Bobberman3]

yea, downgrading Valkyrien Skies down to v2.4.6 worked for me too. I guess its a them issue?

[AlienXtream]

its a known issue that slipped through the cracks. its been mentioned in the discord announcements and discussions a fair bit. TL:DR is VS did some changes to how ship assembling works and clockwork and eureka were unexpectedly affected.

clockwork has since been fixed and eureka is pending a patch. you can either downgrade or use the VS debug tools to assemble (shipify) the structure as temporary solutions. if you have clockwork you can use that one too. everything else works as it should for the most part.
