2a10 Connection to Bolt typed port breaks periodically

Ex-Crow 1 year ago • updated by Lazlo Bonin (Lead Developer) 1 year ago • 2

This connection breaks after each Unity restart since alpha 7 or so. This, however, is not the original graph, I recreated it from 0 in a fresh project so it seems reproducible and should be present in the project I linked in Discord.

Connection can be fixed by rewiring it.

Could not load connection between 'value' of 'IndexerGetMember#28a47...' and 'input' of 'SetBoltClassVariable#1745d...'.

Seems to also break on domain reload.

Hi TowerCrow,

Thanks for the report and sorry for the late reply.

My hypothesis is that this may be due to serialization dependencies. This is why it is inconsistent. Presumably, the asset defining the port's type hasn't been loaded yet when this unit is defined. I'll have to look deeper into this — there are many issues trickling from that caveat.
