[GT] Low - Loss of machines when using correct tool - significant block lag

Kheth

On two separate occasions separated by several hours on 6/21/20 I removed a machine, pipe, and wire using the correct tool only to lose the item. I believe this is a bug as it is accompanied by texture problems and significant block lag.

The issue occurs as follows:
1) A gregtech machine/pipe/wire is removed with the correct tool.
2)The object vanishes without dropping
3)Approximately 5 seconds of block lag occurs, during which I am unable to access backpacks, interact with other machines, etc.
4)For several seconds after the end of the block lag the machine that was removed is replaced by the invalid texture block.
5)After the invalid texture block vanishes, there are several more seconds of block lag and the item is not returned or dropped nearby.

The machine I lost was replaced by Atomicgrog, but since this issue is continuing to occur I thought it worth reporting

The lag spikes lately on GT seem to be coming from world gen, mostly mid game players exploring space/end/etc, so there's not a whole lot we can do about it. It would take 100s of hours of pre-genning and many Terrabytes of disk space to pregen enough of the many, many dims GTNH adds.

As for the GT machine issue, it's been a long standing bug in GT for years. IIRC the issue comes from the vanilla game attempting to skip ticks to catch up during a lag spike. Sometimes that tick happens to include the GT logic that detects if you broke the machine with the right tool/right tier. Sometimes this will destroy the machine, sometimes this will desync your client and turn the machine purple. Trying to break that again will often either crash you client, server, or just destroy the block. Always relog if a block has the purple broken texture.

Going to close this as the item was already refunded and it's not an issue we can fix.
