So anytime i try to pull steam from the fusion reactor it crashes. And ruins the save. Unless i managed to break everything involving the extraction of steam. I am unable to make use of mekanism steam generation.

@hron84 even without openeye, if minecraft crashes due to a forge/mod exception, it will generate a report in the crash-reports folder.

@vedalken254 thanks for heads up, I only know the 1.6 behavior (where crash-reports folder did not exist), some 1.7 features are new for me :-)

Logs.

There are logs? It usually kills the whole client mc stops being a process.

You need to provide the crash report that is saved in crash-reports in the Minecraft directory. Use a service like pastebin and link it here.

@Saizetsu usually, when MC being killed, a crash report is generated. If you have OpenEye in your mod list, find it in crash-reports folder of your minecraft (it lies at same level as mods folder where you copied Mekanism), the file is named like crash-$CURRENT_DATETIME.log where $CURRENT_DATETIME is the date and time when the crash happened. If you do not have OpenEye in your mod list, find the log directory, and upload the latest.log and fml-client-latest.log files to https://gist.github.com and paste the links here. Github Gist takes same account as you used to report this issue, and usually does not require additional login.

Without crash log or any other information, developers aren't able to fix your problem, so I kindly ask to help speed up the process of this problem being fixed by posting your logs, even if you cannot find any relevant info, developers maybe can.
