Ars Mechanica 1.0.5 Closes Crash-Inducing Synchronize Loop
Rufa has issued patch 1.0.5 for Ars Mechanica, addressing a cluster of bugs concentrated in the game's passive skill interactions — including one capable of crashing the game outright.
What changed
Crash fix: A character with the passive skill "Synchronize" receiving a debuff could cause that debuff to bounce indefinitely between synchronized characters, eventually crashing the game. This loop has been resolved.
Buff application fixes: The active skill "Kill Shot" and the passive skills "Ruler" and "Vessel of Souls" were not applying their buffs correctly; this has been corrected.
Behavior change: The passive skill "Battle Fervor" has had its behavior altered. The source does not specify the nature of the change.
Transfer fix: The buff from "Customer Smiles Come First!" was not being transferred correctly by "Synchronize" and now is.
Duration preservation: Buffs extended by the passive skill "Enduring Light" will now retain their extended duration when passed through "Synchronize," rather than reverting to a base duration.
Minor issues: Several additional unspecified fixes are included.
For players who lean on buff-chaining and skill synchronization as core mechanics, this patch restores a level of reliability the systems were clearly not delivering before.
