PreciousBlocks - Rollback

[NiLSPACE]

What would it do,
If lets say Player 1 destroys Player 3's house Player 2 repairs part but not all.
You run a command to rollback Player 3's actions. will it still rollback Player 2's changed as well or ?

then only the changes Player 3 made will be rollbacked. none of the repairs of Player 2 will be changed.

And whats the dept of the changes for the block ?
Aka Player 1 has a house Player 2 destroys it + places new blocks on all the same places and destroys it again(in classic people would often do this to avoid rollbacks on some servers)
Then does it just reverse the last change or will it check the whole log until end to undo all changes done by that user in that region ?

it just reverses the last change of the block. none of the other changes before that. if i somehow managed to do that the .ini file would be much bigger and it would take even longer to initialize the plugin.
