A refund notice is currently visible
When checked on September 27, 2026, the official experience description displayed a tech-tree refund notice. That check date is not a verified release date for the change.
We have not confirmed the refund amount, affected accounts or the current set of nodes. Check the live interface before using a saved build.
Do not rebuild from an old screenshot alone
The promotional image is archival. It is not a verified current node map.
Plan around a measurable problem
- 01
Name the problem
Write down what ended the run: an uncovered angle, a group that escaped your aim, or a mismatch between the build and the route.
- 02
Read the current node
Check the exact wording, prerequisites and cost in the live tree. Avoid applying numbers copied from a different version.
- 03
Make a small test
Change one branch and compare the same encounter. Preserve your earlier notes so that the result has context.
Official archival tree image
The official promotional asset illustrates a branching upgrade system. It does not establish current costs, percentages, refund rules or an optimal sequence.
What a full build guide still needs
A current capture of the entire tree, readable node descriptions, costs and prerequisites, and before-and-after testing are needed before a detailed build can be published.
Older references to a specific node count should not be treated as the current alpha specification without that comparison.
