Projectiles won't work at all

Title: Projectiles won't work at all

Version: 3.1.2

OS: XP SP3 2G Ram

Java Version: JRE 7 Oracle

Description of Problem:

Every single Projectile weapons won't work in tekkit. I am hosting a server and I play on it regularly. For a while, Projectile weapons (Bow, crossbow, Blunderbuss, Musket) worked fine. But at one point while I was using the mining laser, I dug through a floor very quickly, and then I had a "minecraft has run out of memory" message. After that, Projectile weapons just refuse to work.

Whenever I shoot one, one of these things happen:

(Bow) I can see the arrow being shot and flying away, but I quickly pick it up at my feet, as it was never launched. The arrows does multiple trajectories above the first one before landing.

(Crossbow) I charge it, then I shoot it. The bolt goes through the enemy and does no damage, and if I look in 3rd person mode, the bolt hits my head and falls down.

(Blunderbuss/musket) The shots are fired in front of me, but they do no damage.

(Mining Laser) It will refuse to mine unless I shoot down or up.

I have a feeling that any projectiles I shoot ends up shooting me instead and falls directly below me.

I have cleared my cache, re-installed Tekkit entirely (Not the server yet), changed a few settings, but to no avail. Any projectile based item are completely worthless.

To note, EE projectiles (Like Evertide/volcanite/swiftglade) still works.

Error Messages:

"Minecraft has run out of memory"

Okay, now I've done a full re-install of the server. I loaded the Map, and still, the projectiles are broken. Plus, my buildcraft pipes are now bugged and I have to clear them out.

I've tried everything I could to fix this, any feedback would be appreciated.

Other players of my server do not share the same bug that I have. They can still shoot weapons with no problems.

I suppose now it is clear that since my projectiles won't work on my Multiplayer world, so I'll have to restart anew?

I have found the solution!

The watch of Flowing time prevents me from shooting any projectile weapon while in my hotbar. I have tested this on both my server and my single player, and it is consistent.
