When crafting combinator collect recipes game failed because recipe collected but recipe signal not exist

We do not modify the signal item or recipe, so this is likely a result of a different mod. If you include the error message and a mod list I could help point you towards the right place to report this.

Error while running event crafting_combinator_xeraph::on_tick (ID 0)
Unknown virtual-signal name: tiberium-tranmutation-to-aluminum-ore

fixed in crafting_combinator_xeraph

Good to know, I'll include an update in the next version to make placeholder recipes earlier in the process so we are less likely to encounter crashes like this in the future
