One of the crashes (tried starting server multiple times before changing forge config)
crash-2021-01-01_20.52.00-server.txt
):

• Detailed reproduction steps: I placed a turtle with this startup program next to a botania runic altar (turtle inventory would be empty). The program was used for the petal apothecary before I placed it next to the runic altar. The area was chunk loaded with a weirding gadget chunk loader, but I disabled the chunk loader using the weirding gadget config. Even after doing this the server was still crashing:

while true do
    
    local item = turtle.getItemDetail()    
    if item == nil or string.match(item.name, "bucket") == nil then
        print("no bucket")
        break
    end
    if not string.match(item.name, "water") then
        turtle.placeUp()
    end
    while not (rs.getInput("front")) do
        print("pulled")
        os.queueEvent("randomEvent")
        os.pullEvent()
        os.sleep(5)
    end
    if rs.getInput("front") then
        turtle.dropDown()
        print("sleeping")
        os.sleep(1)
        turtle.suckDown()
        print("picked up")
    end
end 

I "fixed" the issue using the forge config to delete erroring tile entities
