Undo button please!

Well today I went straight into slayer. Ranging the rest of my Kurasks from afar, I then got black demons. Noticing I was getting close to that mask I knew I wanted to hurry So I bought a Cannon and went straight to cannoning them. A few minutes after cannoning them I got 77 Range!Right after I finished black demons I thoguht I 2 tasks away so I hurried to Sumona and she gave me banshees, I was excited and rushed to the easy ones in slayer castle, I finished them and thoguht I was four points away, So I went to Vannka. He gave me Sea Snakes and I rushed and killed them and rushed back to Edgeville and back to Vannka. I saw the 400 that first pulls up was still in red and I needed 2 more points! Dangit! I asked for another task from him and I got 66 bloodvelds. I went through the blood alter with my cannon and cannoned them till task complete. I got excited since it was a 10 and gained 20 points, not my usual but oh well.

When I got to Vannka I saw the first 400 I could see was in Green amd I clicked it. I looked and it didn't tell me what to do to make them helm. It said you are better in knowledge of the slayer skill. I got confused until it hit me: There are two 400s! I started freaking out and getting so angry. Wish that Kayla and I's magic undo button worked i looked at my remaning 18 points and got depressed.

Now I only have 18 points and It'll take forever to get all those points back, I'm going to cheat since I am on task 40 and use Vannka until task 50 and use Lapolok, If I countinue this I will get my slayer helm in 23 tasks. I really wish there was an undo button now :(
