One of my server members brought up an issue with the Industrial Electrolyzer. He puts water cells in there, starts processing, goes back to it a few minutes later, and it's not done with the stack, instead the progress arrow is stuck and the machine is pulling high amounts of power from the MFSU he keeps power stored in. Had him make a dedicated line for the machine only, and it still glitches out, not finishing the cell it's processing, and just keeps eating power until the power is all gone, or the machine is dismounted.
Using Forge 395, MC 1.4.5, IC2 1.09 build 133lf, and Gregtech Mod version (let me go open the freakin file, extract the info file and find out... kind of obnoxious as hell it's the only mod that DOESN'T outright state its version...) 2.50C.
Can PM ya a copy of a link to a dropbox copy of the server's current client ifin you'd like.
Edit: Was unable to get the issue to happen in SSP testing, but happens every time in SMP after approx a stack of water cells... very wierd.
Also, love the hell out of the mod. Any chance you might make another tier up of EU storage, maybe has items in it that take upwards of a week to process a single part... (love super end game stuffs, haha)
