Was running 132 version on 1.11.2 MC.

Upgraded server to 1432 version, and server crashes during bootup while executing Rec Complex init.

1.4.3.2 is, as listed on curse, for MC 1.12. 1.4.3.1 is the same for MC 1.11.

Thanks for the update...

Are you sure the version checking is correct then? Because I don't think I was getting the "wrong version" error that I would normally get, but rather other errors.

As far as having the wrong version - that actually happened with several others yesterday. I think there's a glitch on Curse that downloads the wrong one sometimes. I actually watched one twice in a row when I clicked on the 1.11 version actually downloaded the 1.12 instead. First time I thought I misclicked, second time I actually watched it download the wrong file. Several downloaded the 1.10 versions when I clicked on the 1.11.... of course none of that is anything you can fix. But likely how I ended up with the wrong version.

I'd report that to curse maybe. ReC doesn't have an internal MC version check - which I should maybe change some time.
