CURRENT MEKANISM ISSUES!
Right now, there are two issues with Mekanism that can cause crashes : The Electrical Pump, and Logic Transport Pipes.
If you are crashing with
Code:
java.lang.NullPointerException
at mekanism.common.FluidNetwork.tickEmit(FluidNetwork.java:158) ~[FluidNetwork.class:?]
UPDATE Mekanism to 8.1.1.225
If you are crashing with
Code:
java.lang.NullPointerException: Ticking block entity
at mekanism.common.content.transporter.TransporterPathfinder.getPaths(TransporterPathfinder.java:227)
DOWNGRADE Mekanism to 8.1.0.216
IN EITHER CASE : Switch to another pipe (enderIO conduits work well) and pump until Mekanism has a solid dev version that fixes these issues.
EDIT : NEW VERSION NOTE
Do NOT update to 8.1.2. Right now, this is only compatible on latest forge versions (1395+), which is something we cannot update to yet.
Around Forge 1350ish, the Fluid API changed, and many mods we use crash due to these changes, and they haven't been updated to the new Fluid API.
