What should I verify before continuing after a major update?

Direct answer

Read the current official announcement, list every changed system your plan depends on, and test those dependencies before spending or moving important assets. Preserve the old plan until the new behavior is confirmed in the intended scenario.

Decision signal	What to verify	Next move
Patch affects a dependency	Map the change to build, base, or scenario	Test the affected layer first
Migration changes access	Confirm character and server eligibility	Avoid irreversible moves based on old rules
Performance appears different	Repeat the same controlled activity	Separate patch impact from changed conditions

Decision checklist

Read the latest official update and bug-fix notices
List changed systems used by the current plan
Record important character, inventory, and base state
Test one affected dependency in a low-cost activity
Update the plan only after the result repeats

Stop and recheck when

Stop when the official note does not cover an irreversible transition
Roll back the planned investment when the core interaction is unverified

Common mistakes

Changing the complete build from patch headlines
Assuming old scenario rules still apply
Using community speculation as confirmation of carryover
