Me and my friends are using the Transportation mod in a mod pack. We have added it to this specific modpack before but have picked it up again. Nothing has changed (No extra mods different from last time) that we know of but suddenly whenever players leave the chunk the sorting system stops working. By stops working I mean:

• Player will be able to use system fine
• Player will leave the chunk
• Upon reloading the chunk and going to use the system the UI will show up with the items but when requesting item it never comes
• To fix the issue you can break any pipe and replace it for it to work

Anyone know if we have done something wrong or if this is a bug?

After some messing around we realised it was because the pipes crossed chunk boarders. I hope this is fixed in later versions.
