Variable in state temp don't be sent anymore on last node

Describe the bug I'm trying to upgrade botpress server from v12.22.2. I have a bot which store variable in state/temp on several nodes of the bot. At the end, we get all these variables for avanced usage. (We access to the bot via API) In all version i tested (12.23.0, 12.26.0, 1.26.12, 12.29.1, 12.30.6), i can see with the studio debugger (for lastest version) that the variable are correctly set all the way in the bot. But when arriving on the last one, all variable are deleted.

To Reproduce Make a bot with node which store variable. (bot_test_1671111461712.zip) Navigate in it. The state/temp contains all variables.
Go to the end on the tree and the state/temp is empty.

Expected behavior The state/temp contains all variable even at the end so we can use them like in version 12.22.2.
